Microsoft’s consumer-facing Copilot rollout has landed the company in federal court in Australia after the Australian Competition and Consumer Commission (ACCC) accused Microsoft of misleading roughly 2.7 million subscribers by bundling Copilot into Microsoft 365 personal and family plans while obscuring a cheaper “Classic” alternative and prompting customers to accept higher renewal prices or cancel.
Microsoft began integrating its generative AI assistant, Copilot, into consumer Microsoft 365 subscriptions in late 2024 and completed a wider rollout in January 2025. The company positioned Copilot as a productivity upgrade across Word, Excel, PowerPoint, Outlook and other consumer apps—an addition that it said justified higher subscription pricing. In Australia, this change translated into a 45% increase for the Personal plan (from A$109 to A$159) and a 29% increase for the Family plan (from A$139 to A$179), figures the ACCC highlights in its court filing.
The ACCC filed proceedings in the Federal Court on 27 October 2025, accusing Microsoft Australia Pty Ltd and Microsoft Corporation of conveying a false or misleading impression to subscribers with auto-renew enabled: that their only choices were to accept the Copilot-integrated, higher-priced plans or cancel their subscription. The regulator says a third option—the Microsoft 365 Personal Classic and Family Classic plans, which preserved the previous features and price—was available but not disclosed in the notices that mattered.
It’s important to note what is—and isn’t—proven. The ACCC has produced screenshots and a concise statement; those materials underpin its claim that the Classic option was only visible deep in the cancellation flow. Conversely, Microsoft can point to contemporaneous support articles and product pages that mention alternatives. The legal battle will pivot on the reasonable consumer standard: whether the average subscriber, relying on the notices sent, would have believed they had only the two choices the ACCC says Microsoft presented.
Possible remedies include:
For users, the practical takeaway is straightforward: review subscription notices carefully and check your account SKU before renewal. For vendors, the message is equally clear: monetizing AI is legitimate, but transparency and well-documented communication practices are now enforceable priorities.
The ACCC’s action raises fundamental questions about how much discretion large platforms may exercise when reconfiguring product tiers and price structures. Its outcome will likely shape product rollout playbooks and regulatory expectations globally—making this one of the most important tests yet of how consumer protection law adapts to an AI-first product economy.
Australia’s lawsuit does more than contest a single pricing change; it forces a legal and moral reckoning over how companies communicate the costs of AI to everyday users. The Federal Court proceeding will determine not only whether Microsoft’s communications were misleading under Australian law, but also how firms should design transparency into subscription-driven AI features in years to come.

Background
Microsoft began integrating its generative AI assistant, Copilot, into consumer Microsoft 365 subscriptions in late 2024 and completed a wider rollout in January 2025. The company positioned Copilot as a productivity upgrade across Word, Excel, PowerPoint, Outlook and other consumer apps—an addition that it said justified higher subscription pricing. In Australia, this change translated into a 45% increase for the Personal plan (from A$109 to A$159) and a 29% increase for the Family plan (from A$139 to A$179), figures the ACCC highlights in its court filing. The ACCC filed proceedings in the Federal Court on 27 October 2025, accusing Microsoft Australia Pty Ltd and Microsoft Corporation of conveying a false or misleading impression to subscribers with auto-renew enabled: that their only choices were to accept the Copilot-integrated, higher-priced plans or cancel their subscription. The regulator says a third option—the Microsoft 365 Personal Classic and Family Classic plans, which preserved the previous features and price—was available but not disclosed in the notices that mattered.
What the ACCC alleges: the case in plain terms
The communications at issue
The ACCC’s complaint focuses on specific communications—two targeted emails and a blog post—that Microsoft used to notify customers of the Copilot integration and price change. The regulator says those materials created a binary choice and failed to disclose the Classic plans that retained the older pricing and functionality. Screenshots included in the ACCC’s initiating documents show the Classic option appearing only later in the cancellation flow, a timing the ACCC contends was deliberate and materially misleading to a reasonable consumer.The alleged harm
The ACCC frames the harm as both economic and informational. Economically, millions of Australians may have renewed at a substantially higher price for features they did not want or use. Informationally, consumers were denied a clear, contemporaneous choice that would have allowed them to keep their prior plan and price. The scale of the alleged harm—approximately 2.7 million affected accounts, according to the regulator—gives the case obvious public-interest weight.Microsoft’s position and the contested facts
Microsoft has said it is reviewing the ACCC’s claims and points to public-facing blog posts and support pages that documented Copilot’s inclusion and routes for existing subscribers to switch to non-Copilot options, such as Microsoft 365 Basic or the Classic SKUs for a limited time. The core dispute is therefore not whether Classic plans existed, but whether Microsoft’s specific communications to auto-renewing customers were sufficiently clear and prominent to avoid misleading them.It’s important to note what is—and isn’t—proven. The ACCC has produced screenshots and a concise statement; those materials underpin its claim that the Classic option was only visible deep in the cancellation flow. Conversely, Microsoft can point to contemporaneous support articles and product pages that mention alternatives. The legal battle will pivot on the reasonable consumer standard: whether the average subscriber, relying on the notices sent, would have believed they had only the two choices the ACCC says Microsoft presented.
Why this matter matters: subscription law, UX design, and AI monetization
A test case for modern subscription practices
This litigation is a bellwether for how regulators will treat the monetization of AI features inside subscription products. Companies increasingly fold AI into core services and shift pricing to support the significant operational costs of running large models. That practice raises questions about transparency, consumer consent, and the design of opt-out pathways. Regulators will increasingly expect explicit, prominent disclosures when material product changes affect billing.Dark patterns and disclosure design
The ACCC’s allegations echo a wider global concern about dark patterns: interface designs that nudge users toward choices beneficial to the provider but not necessarily obvious to the consumer. Burying a cheaper, functionally equivalent option behind a cancellation flow may be lawful in some contexts, but it becomes problematic under consumer protection laws if it results in a materially misleading impression at the moment consumers make renewal decisions. The court will examine not just the wording of emails but the user journey—what a subscriber actually sees and when they see it.Potential penalties and remedies
Under Australian Consumer Law, penalties for corporations can be substantial: the greater of A$50 million, three times the benefit obtained from the conduct, or 30% of adjusted turnover during the breach period if the benefit cannot be calculated. The ACCC is seeking penalties, injunctions, consumer redress and legal costs. If the court finds repeated contraventions, the aggregate exposure could be material despite Microsoft’s global scale.Possible remedies include:
- Monetary penalties assessed per contravention.
- Consumer redress (refunds, credits or other forms of restitution).
- Injunctions or court orders to change how Microsoft communicates subscription changes.
- Costs and other compliance undertakings.
What the ACCC’s evidence looks like
The ACCC’s initiating materials include a concise statement and screenshots capturing:- The notification emails and blog post language.
- The account cancellation flow showing when the Classic plan option was surfaced.
- Examples of consumer complaints and forum reports that informed the regulator’s investigation.
Strengths of the ACCC’s case
- Concrete artifacts: The ACCC relies on specific emails, a blog post and screenshots of the account flow—materials that can be objectively examined in court.
- Scale of impact: The alleged 2.7 million affected customers and double‑digit percentage price increases provide quantifiable consumer harm.
- Regulatory capacity: The ACCC has prior experience litigating complex digital-economy matters and is well resourced for evidence-driven enforcement.
Microsoft’s likely defenses and weak points in the ACCC’s claim
- Public support pages and posts: Microsoft can point to published blog entries and help articles that documented the Classic plans and other non-Copilot options, arguing that reasonable notice existed.
- Variation in user experiences: Public reports show inconsistent customer journeys; some users saw and switched to Classic without issue while others report the higher renewal processed despite notices. This heterogeneity may complicate claims of systemic deception.
- Intent vs consequence: The ACCC alleges deliberate concealment. Proving intent is harder than proving misleading conduct; absent internal directives or emails, the ACCC may need to rely on circumstantial evidence and the practical effect of Microsoft’s communications.
Wider implications for product teams and compliance
This case is already a useful checklist for product managers, legal teams and UX designers:- Lead with clarity: Material changes that affect pricing should list all available alternatives and their relative costs in the opening lines of renewal notices.
- Avoid burying opt-outs: If a legacy or lower-cost plan exists, present it clearly within the same communication, not hidden in a cancellation flow.
- Document decision-making: Retain internal records that explain why a communication was structured a certain way, including legal sign-offs and consumer-impact testing.
- Audit the UX funnel: Test subscription renewal and cancellation flows under realistic conditions to ensure alternatives are discoverable in ordinary user journeys.
- Prepare for discovery: Assume regulators will request logs, click-path analytics and internal comms during discovery in any enforcement action.
How subscribers and IT buyers should respond now
- Review your renewal dates and subscription SKU in your Microsoft account.
- Check whether you’re on a Copilot‑enabled or Classic plan before your next renewal.
- Preserve communications and screenshots if you think you were charged unexpectedly—those records are useful for regulators or for any redress process.
Risk assessment for Microsoft and the industry
Reputational risk
Allegations that a company intentionally obscured cheaper options in a renewal notice cut to consumer trust—the very currency vendors need when introducing paid AI features. Even if Microsoft avoids a large penalty, the reputational damage and loss of goodwill could produce long-term churn or opportunistic migration to alternatives.Regulatory ripple effects
A finding for the ACCC could embolden regulators in other jurisdictions to apply similar scrutiny to AI rollouts and subscription changes, prompting coordinated enforcement or prompting lawmakers to tighten rules around renewal notices and default opt‑ins. The design of opt-out pathways and the placement of price-change disclosures may become formalized compliance checkpoints.Operational cost and product redesign
If the court orders changes to how Microsoft communicates pricing or mandates refunds/redress, the company could incur meaningful remediation costs—as well as the operational burden of redesigning global notification flows to meet jurisdictional requirements.What remains unverified (and why it matters)
The ACCC alleges that Microsoft deliberately omitted references to Classic plans to increase uptake of higher-priced Copilot subscriptions. Evidence of deliberate corporate intent—internal plans, emails or executive directives—has not been publicly disclosed and remains within Microsoft’s control. Any assertion about motive should therefore be treated with caution until discovery reveals supporting documents or testimony. The public record so far shows strong circumstantial evidence (timing, screenshots and user complaints), but intent is a legal standard that may require deeper proof.Timeline and what to watch next
- 27 October 2025: ACCC commenced Federal Court proceedings and uploaded a concise statement and initiating documents.
- Immediate next steps: Microsoft will formally respond in court; directions hearings and discovery requests will follow. Discovery could surface internal communications that materially shape the case.
- Possible outcomes: negotiated settlement with undertakings and redress, trial with final judgment, or dismissal on factual/legal grounds.
Final analysis: what this case signals for Windows users and the broader market
This litigation is a lightning rod at the intersection of subscription economics, UX design and consumer protection in the AI era. Microsoft’s integration of Copilot reflects a wider industry move to monetize AI through existing subscription bundles, and regulators are signaling that such rollouts must be accompanied by clear, contemporaneous disclosures that allow consumers to make informed choices.For users, the practical takeaway is straightforward: review subscription notices carefully and check your account SKU before renewal. For vendors, the message is equally clear: monetizing AI is legitimate, but transparency and well-documented communication practices are now enforceable priorities.
The ACCC’s action raises fundamental questions about how much discretion large platforms may exercise when reconfiguring product tiers and price structures. Its outcome will likely shape product rollout playbooks and regulatory expectations globally—making this one of the most important tests yet of how consumer protection law adapts to an AI-first product economy.
Australia’s lawsuit does more than contest a single pricing change; it forces a legal and moral reckoning over how companies communicate the costs of AI to everyday users. The Federal Court proceeding will determine not only whether Microsoft’s communications were misleading under Australian law, but also how firms should design transparency into subscription-driven AI features in years to come.
