Australia’s competition regulator has launched a high‑stakes Federal Court action against Microsoft, alleging the company deliberately concealed a lower‑cost Microsoft 365 option when it bundled its Copilot generative‑AI assistant into consumer subscriptions and raised renewal prices — conduct the ACCC says misled roughly 2.7 million Australian customers.
Microsoft began broad consumer rollouts of Copilot — its generative‑AI assistant for Word, Excel, PowerPoint, Outlook and related apps — in late 2024, with a formal integration into Microsoft 365 Personal and Family subscriptions from 31 October 2024. The addition was accompanied by notable Australian retail price changes: the annual Microsoft 365 Personal plan rose from A$109 to A$159, and Microsoft 365 Family moved from A$139 to A$179. The Australian Competition and Consumer Commission (ACCC) says those figures underpin the alleged economic harm.
The ACCC filed proceedings on 27 October 2025, naming Microsoft Australia Pty Ltd and Microsoft Corporation and seeking penalties, injunctions, declarations and consumer redress under the Australian Consumer Law. The regulator has framed its claim around the specific communications Microsoft used — two targeted emails to auto‑renewing customers and a public blog post — and the design of Microsoft’s account flows that, the ACCC alleges, hid a contemporaneous “Classic” no‑Copilot option behind a cancellation pathway.
Key factual assertions the ACCC will rely on include:
The factual dispute the Federal Court will resolve is not whether Classic SKUs existed — Microsoft publicly documented non‑Copilot alternatives and support pages that referenced them — but whether the specific renewal notices and the user‑journey experienced by auto‑renewing subscribers were sufficiently clear and prominent to avoid creating a misleading impression. The ACCC says that for many customers the Classic option was effectively discoverable only by initiating cancellation, which transformed a transparent opt‑in model into a de‑facto opt‑out design.
Expect the litigation to follow a standard Federal Court pathway but with accelerated discovery and evidentiary skirmishes over internal communications, UX test logs, telemetry, and consumer complaints. The ACCC will likely seek internal Microsoft documents showing the rationale behind the design choice that placed the Classic option in a cancellation flow, as well as analytics demonstrating where customers saw or failed to see alternatives. Microsoft will counter with public communications, support documentation, and possibly evidence that the Classic option was available and described for consumers.
Notably, a UK collective action filed in December 2024 alleged Microsoft overcharged UK businesses for Windows Server when used on rival cloud platforms, claiming more than £1 billion in damages. That legal action and related complaints to competition authorities in Europe and the U.S. reflect an intensified international focus on how dominant vendors price software and structure bundles.
Those parallel pressures increase the reputational and compliance stakes for Microsoft. A finding against Microsoft in Australia would not automatically translate into liability elsewhere, but it would strengthen regulatory arguments that certain design choices are systemic rather than jurisdictional one‑offs. Conversely, a favourable outcome for Microsoft would reinforce the company’s argument that public disclosures and support documentation satisfy legal requirements — putting the emphasis back on consumer behaviour and the reasonable consumer standard rather than prescriptive UX rules.
Microsoft’s plausible defenses include:
For consumers and IT professionals, the practical takeaway is simple: when subscription terms change and prices rise, the clarity of communications at the renewal decision point matters — and regulators are prepared to litigate where they believe design or disclosure choices have crossed the line.
For Microsoft, the case will force a careful reckoning between product packaging, pricing strategy and the legal obligations that accompany large‑scale, subscription‑based monetisation of AI. The Federal Court’s handling of discovery and the trial will shape how tech vendors design renewal journeys and notify customers about material changes in the AI era.

Microsoft began broad consumer rollouts of Copilot — its generative‑AI assistant for Word, Excel, PowerPoint, Outlook and related apps — in late 2024, with a formal integration into Microsoft 365 Personal and Family subscriptions from 31 October 2024. The addition was accompanied by notable Australian retail price changes: the annual Microsoft 365 Personal plan rose from A$109 to A$159, and Microsoft 365 Family moved from A$139 to A$179. The Australian Competition and Consumer Commission (ACCC) says those figures underpin the alleged economic harm. The ACCC filed proceedings on 27 October 2025, naming Microsoft Australia Pty Ltd and Microsoft Corporation and seeking penalties, injunctions, declarations and consumer redress under the Australian Consumer Law. The regulator has framed its claim around the specific communications Microsoft used — two targeted emails to auto‑renewing customers and a public blog post — and the design of Microsoft’s account flows that, the ACCC alleges, hid a contemporaneous “Classic” no‑Copilot option behind a cancellation pathway.
What the ACCC alleges — the case in plain terms
The ACCC’s complaint advances a narrow but legally significant theory: Microsoft’s renewal notices conveyed a binary choice — accept the Copilot‑integrated, higher‑priced subscription or cancel — while failing to disclose a third, materially different option: Microsoft 365 Personal Classic and Microsoft 365 Family Classic, which preserved the prior features and pricing without Copilot. The regulator says the Classic option only became visible after a customer began the cancellation process in their Microsoft account, effectively hiding the choice from many auto‑renewing subscribers.Key factual assertions the ACCC will rely on include:
- Approximately 2.7 million Australian Microsoft 365 Personal and Family subscribers are potentially affected.
- The consumer rollout and price movements tied to Copilot integration: Personal annual price from A$109 → A$159 (≈ +45%); Family annual price from A$139 → A$179 (≈ +29%).
- Central communications under scrutiny: two targeted emails to auto‑renewing subscribers and a product blog post announcing Copilot and price changes.
Microsoft’s response and the contested facts
Microsoft has said it is reviewing the ACCC’s claims and stressed that consumer trust and transparency are top priorities, promising to work constructively with the regulator. That statement, while short, signals it will contest the ACCC’s framing rather than concede facts at this early stage. Independent outlets that covered the filing noted Microsoft’s response and the company’s prior public documentation of subscriber options.The factual dispute the Federal Court will resolve is not whether Classic SKUs existed — Microsoft publicly documented non‑Copilot alternatives and support pages that referenced them — but whether the specific renewal notices and the user‑journey experienced by auto‑renewing subscribers were sufficiently clear and prominent to avoid creating a misleading impression. The ACCC says that for many customers the Classic option was effectively discoverable only by initiating cancellation, which transformed a transparent opt‑in model into a de‑facto opt‑out design.
Legal framework and likely remedies
Under the Australian Consumer Law (ACL), businesses must not engage in conduct that is misleading or deceptive, including the omission of material information that would influence consumer decisions. The ACCC is seeking remedies available under the ACL: declarations, injunctions, orders for consumer redress and civil penalties. The maximum statutory penalty for each contravention is the greater of A$50 million, three times any benefit obtained, or 30% of adjusted turnover for the relevant period where benefits cannot be calculated. The precise quantum would depend on what the Court finds at trial.Expect the litigation to follow a standard Federal Court pathway but with accelerated discovery and evidentiary skirmishes over internal communications, UX test logs, telemetry, and consumer complaints. The ACCC will likely seek internal Microsoft documents showing the rationale behind the design choice that placed the Classic option in a cancellation flow, as well as analytics demonstrating where customers saw or failed to see alternatives. Microsoft will counter with public communications, support documentation, and possibly evidence that the Classic option was available and described for consumers.
Why this matters: subscriptions, AI monetisation, and dark patterns
This case sits at the intersection of three contemporary trends:- The rapid monetisation of AI features inside established subscription products. Companies are embedding generative AI into core apps and adjusting price and packaging to cover higher compute costs and to segment users by value. Regulators are now scrutinising how those monetisation moves are communicated.
- The legal and consumer impact of recurring billing and default renewals. Auto‑renew inertia is well known: many subscribers will not act unless prompted in a way that is clear and discoverable. That reality raises the bar for clarity when price increases or materially different bundles are introduced.
- The regulatory focus on choice architecture and dark patterns. UX flows that nudge consumers toward pricier options—especially by burying cheaper alternatives—are increasingly viewed as potential consumer law problems. The ACCC’s complaint is effectively testing where the line sits between aggressive commercial design and unlawful omission.
Broader regulatory context and Microsoft’s global legal landscape
The ACCC’s case will not be considered in isolation. Microsoft faces growing regulatory and private litigation scrutiny across jurisdictions over competitive practices, licensing and the monetisation of core products.Notably, a UK collective action filed in December 2024 alleged Microsoft overcharged UK businesses for Windows Server when used on rival cloud platforms, claiming more than £1 billion in damages. That legal action and related complaints to competition authorities in Europe and the U.S. reflect an intensified international focus on how dominant vendors price software and structure bundles.
Those parallel pressures increase the reputational and compliance stakes for Microsoft. A finding against Microsoft in Australia would not automatically translate into liability elsewhere, but it would strengthen regulatory arguments that certain design choices are systemic rather than jurisdictional one‑offs. Conversely, a favourable outcome for Microsoft would reinforce the company’s argument that public disclosures and support documentation satisfy legal requirements — putting the emphasis back on consumer behaviour and the reasonable consumer standard rather than prescriptive UX rules.
What discovery will likely reveal (and what to watch for)
The courtroom battle will hinge heavily on documentary and forensic evidence. Expect the following to play out:- Internal product and pricing memos that show how Microsoft decided on Copilot packaging and where Classic SKUs should appear in flows.
- Email templates and support articles — timing, wording and distribution logs — to test whether the two emails and blog post the ACCC cites actually did omit reference to Classic plans for materially relevant cohorts.
- Analytics and telemetry showing click‑through rates and how many auto‑renewing customers were presented with the Classic option before renewal versus after initiating cancellation.
- Consumer complaints, forum posts and help‑desk tickets the ACCC used to corroborate real‑world effects. The regulator said consumer reports and online comments were part of its investigation.
Practical advice for Microsoft 365 customers (and WindowsForum readers)
- Check your subscription page: navigate to account.microsoft.com → Services & subscriptions and confirm what plan is currently active and whether a Classic or non‑Copilot SKU is available for your account. The ACCC’s own guidance noted that some users who had not renewed since July 8, 2025, may be able to revert via the cancellation sequence.
- Preserve evidence: if you believe you were affected, retain renewal emails, screenshots of account pages, billing statements and communications with Microsoft. These are the materials regulators and courts request.
- Review billings and bank statements: determine whether auto‑renewals occurred at the higher Copilot‑integrated price and calculate any potential overpayments. If you find anomalies, contact Microsoft support and consider lodging a formal complaint with the ACCC if you are an Australian resident.
- Consider switching to a single‑payment offline product if you depend on Office for critical tasks and prefer not to have ongoing subscription changes; Microsoft still offers perpetual Office licences in select channels, though their feature set and update cadence differ from Microsoft 365. This is a product trade‑off rather than a legal remedy.
The commercial and reputational stakes for Microsoft
The ACCC’s civil penalties regime means exposure could be sizable in the abstract, but the real material risk to Microsoft is reputational and operational:- A penalty or mandated redress program could produce a multi‑million dollar payment and a public remediation mechanism that forces Microsoft to rework communications globally.
- A judicial finding that Microsoft used choice architecture to nudge consumers could invite parallel regulatory enforcement or private litigation in other markets, especially where similar product rollouts and billing models exist.
- Operationally, Microsoft may have to change in‑product flows and renewal notices to ensure contemporaneous disclosure — a non‑trivial redesign across regions and languages.
Critical analysis — strengths of the ACCC’s approach and Microsoft’s likely defenses
The ACCC’s case is methodical: it ties concrete communications (two emails and a blog post), specific dates (Copilot integration effective 31 October 2024), quantifiable price moves and consumer complaints to build a narrative that an omission was material and consequential. That documentary focus is a legal strength: courts dislike speculative theories that lack tied‑to‑evidence hooks. The regulator’s estimate of 2.7 million affected accounts — while headline‑grabbing — is rooted in Microsoft’s subscriber base and the cohort of auto‑renewing Personal and Family plans.Microsoft’s plausible defenses include:
- Asserting that public documentation (blog posts and support pages) did disclose the Classic options, and that those disclosures satisfy the standard of non‑misleading conduct.
- Arguing the reasonable consumer standard: that most subscribers are put on notice by prominent communications and that those who missed an alternative did so through inattention rather than corporate concealment.
- Demonstrating that the Classic plans were operationally available and that the cancellation flow was one of several routes to access alternatives, not the only route.
What comes next — procedure and timing
Federal Court proceedings will move through pleadings, discovery and interlocutory hearings. Given the technical nature of the evidence — UX screenshots, telemetry, email logs — expect intensive discovery disputes and expert testimony on user behaviour. Interim remedies are possible but unlikely at this early stage; the more probable sequence is months of document disclosure followed by contested factual and expert evidence. Regulators in other jurisdictions will watch closely, and consumer groups may use any Court findings to mount follow‑on claims elsewhere.Conclusion
The ACCC’s action against Microsoft is a timely and detailed test of how consumer protection law applies to the monetisation of AI inside subscription products. At stake are not just potential penalties and redress for Australian Microsoft 365 subscribers, but a legal precedent about the discoverability of alternatives, the permissible boundaries of choice architecture, and the obligations companies face when they fold powerful new features — and higher prices — into everyday software.For consumers and IT professionals, the practical takeaway is simple: when subscription terms change and prices rise, the clarity of communications at the renewal decision point matters — and regulators are prepared to litigate where they believe design or disclosure choices have crossed the line.
For Microsoft, the case will force a careful reckoning between product packaging, pricing strategy and the legal obligations that accompany large‑scale, subscription‑based monetisation of AI. The Federal Court’s handling of discovery and the trial will shape how tech vendors design renewal journeys and notify customers about material changes in the AI era.
