Google’s abrupt decision to withdraw its formal antitrust complaint against Microsoft in the European Union is the clearest signal yet that the dispute over cloud competition has shifted from company-level litigation toward regulatory enforcement under the Digital Markets Act (DMA), handing the initiative to Brussels and dramatically widening the potential scope and stakes of any remedy.
The original complaint was lodged by Google Cloud in 2024, alleging that Microsoft’s licensing and pricing practices for Windows Server, Office, and related products effectively locked customers into Azure and imposed punitive costs on businesses that sought to run Microsoft software on rival cloud platforms. Google argued these practices undermined competition and raised barriers for rivals such as Google Cloud and other European cloud providers. Over the past month the European Commission announced the launch of three DMA-driven market investigations into the cloud sector aimed at assessing whether Amazon Web Services and Microsoft Azure act as “important gateways” and whether DMA remedies can address contractual and technical practices that impair competition and portability. That announcement changed the enforcement calculus: market investigations under the DMA offer ex‑ante regulatory powers and a broader toolkit than a standalone antitrust complaint. Inside community channels and technical forums the news was reflected as an immediate pivot in strategy — a retreat from bilateral complaint-driven pressure and a hand-off to the Commission’s formal, sector-wide review. Forum summaries and internal briefings noted that Google’s withdrawal coincided with Brussels’ announcement and was framed by Google as a pragmatic step in light of the Commission’s new market probe.

Background
The original complaint was lodged by Google Cloud in 2024, alleging that Microsoft’s licensing and pricing practices for Windows Server, Office, and related products effectively locked customers into Azure and imposed punitive costs on businesses that sought to run Microsoft software on rival cloud platforms. Google argued these practices undermined competition and raised barriers for rivals such as Google Cloud and other European cloud providers. Over the past month the European Commission announced the launch of three DMA-driven market investigations into the cloud sector aimed at assessing whether Amazon Web Services and Microsoft Azure act as “important gateways” and whether DMA remedies can address contractual and technical practices that impair competition and portability. That announcement changed the enforcement calculus: market investigations under the DMA offer ex‑ante regulatory powers and a broader toolkit than a standalone antitrust complaint. Inside community channels and technical forums the news was reflected as an immediate pivot in strategy — a retreat from bilateral complaint-driven pressure and a hand-off to the Commission’s formal, sector-wide review. Forum summaries and internal briefings noted that Google’s withdrawal coincided with Brussels’ announcement and was framed by Google as a pragmatic step in light of the Commission’s new market probe.What exactly happened: timeline and mechanics
- September 25, 2024 — Google Cloud publicly filed an antitrust complaint with the European Commission about Microsoft’s cloud licensing and pricing practices, laying out claims that those terms punished customers who ran Microsoft workloads on competing clouds.
- November 18, 2025 — The European Commission launched three DMA-based market investigations into cloud computing services, explicitly signalling the Commission’s intent to evaluate whether AWS and Microsoft Azure should be treated as DMA “gatekeepers” or whether DMA obligations should be adapted to the cloud sector.
- November 28, 2025 — Google announced it had withdrawn the EU antitrust complaint against Microsoft, citing the Commission’s market investigations and the belief that Brussels’ broader probe would better address the structural issues Google had raised. Major news outlets reported the withdrawal the same day.
Why Google pulled the complaint: tactical and practical reasoning
At a tactical level, withdrawing the complaint reduces the risk of parallel or fragmented proceedings that could produce inconsistent remedies. Google’s public messaging — updated on its Cloud blog — said the company would continue to press for openness and choice in cloud markets but that the DMA market investigations provide a superior pathway to address the structural barriers it complained about. From a practical perspective, DMA market probes empower the Commission to explore:- Gatekeeper designation — which carries specific, enforceable obligations.
- Sector-wide remedies — that can require interoperability, non-discriminatory access, and greater portability.
- Faster ex-ante measures — designed to prevent harm before it crystalizes into entrenched lock-in.
The DMA investigations: scope, powers, and what’s new
The European Commission’s November 18 announcement launched three distinct lines of inquiry:- A market investigation into Amazon Web Services (AWS).
- A market investigation into Microsoft Azure.
- A thematic probe assessing how the DMA’s tools can be applied to cloud markets — specifically looking at interoperability, data access, bundling, and contractual terms that may unfairly favour incumbents.
What Google and Microsoft have said publicly
Google framed its withdrawal as a pragmatic choice: its blog post states the complaint was lodged to amplify customer concerns about restrictive cloud licensing and that Google will continue to engage with policymakers and regulators across the EU as the DMA probe proceeds. Google emphasized its continued advocacy for “choice and openness” and confirmed it is withdrawing the complaint “in light of the recent announcement that the EC will assess problematic practices affecting the cloud sector under a separate process.” Microsoft issued a shorter public response in prior coverage—pointing to settlements reached with certain cloud trade groups and arguing its commercial practices are lawful and competitive. Microsoft’s stance has been that the cloud market is dynamic and competitive, and that prior settlements addressed many of the practical issues raised by other complainants. Microsoft has consistently denied that it uses its software business to unfairly favour Azure. Media coverage summarized Google’s withdrawal as both a retreat from a head-to-head complaint and a strategic move that hands the regulatory initiative to Brussels, where the Commission’s DMA powers could deliver broader remedies than a single antitrust action.What’s at stake — commercial and strategic implications
The cloud market is the backbone of modern enterprise IT, and the outcome of this probe could reshape how cloud providers compete, price, and package software. Current market shares are relevant context: estimates place AWS at roughly 30% global market share, Microsoft Azure around 20%, and Google Cloud near the low teens — a distribution that frames the Commission’s concern about potential “gateway” effects. If DMA remedies require structural or technical changes, they could affect:- Licensing and pricing for Windows Server and Office products.
- Contractual exit costs and portability mechanisms for enterprise customers.
- Competitive parity in managed services and AI-related cloud tooling.
Legal contours: antitrust complaint vs DMA market probe
Antitrust cases typically pursue remedies after harm is established and often focus on specific conduct by a single company. DMA investigations, by contrast, are ex‑ante and systemic: they can impose obligations designed to prevent anti‑competitive outcomes before dominance fully ossifies. That distinction matters because:- Antitrust enforcement is reactive and remedial.
- DMA enforcement is proactive and prescriptive.
Technical issues the Commission will probe
The Commission has signalled several technical areas of interest that were central to Google’s original complaint and that matter for cloud competition:- Interoperability: whether APIs, hypervisor integrations, and licensing policies enable or hinder true workload portability.
- Data portability and access: how easy it is for customers to extract data and move live services between clouds without unacceptable downtime or cost.
- Contractual terms and exit fees: whether commercial clauses make migration impractical or prohibitively expensive.
- Tying and bundling: whether Microsoft ties critical software features to Azure-specific functionality in a way that forecloses rivals.
Strengths of the Commission-led route
- Broader remedial toolkit: DMA remedies can be structural, technical, and behavioural — and can be applied sector-wide rather than company-by-company.
- Faster preventative powers: ex‑ante obligations can be imposed to stop harmful conduct before it becomes entrenched.
- Sectoral view: the Commission can examine systemic lock-in mechanisms and the ecosystem effects across multiple providers, customers, and intermediaries.
Risks, weaknesses, and open questions
- Political and legal complexity: applying the DMA to cloud infrastructure is legally novel and will invite intense technical and legal pushback from hyperscalers. Expect protracted disputes over definitions—what counts as an “important gateway,” how to measure network effects, and where regulation could unintentionally harm innovation.
- Operational risk for customers: sudden enforcement actions or ill‑designed interoperability mandates could create migration risk and service disruption for large enterprise customers if not phased carefully.
- Enforcement uncertainty: the DMA’s application to infrastructure raises thorny questions about technical feasibility and costs; regulators may need to calibrate remedies to avoid perverse outcomes that raise prices or reduce innovation.
- Evidence and burden: Google’s withdrawal does not mean the evidence is conclusive; the Commission’s investigators still must determine whether practices materially limit contestability — and those determinations will be contested. If evidence falls short, the Commission could conclude that tailored remedies, rather than gatekeeper obligations, are more appropriate.
Reputational and market consequences for Microsoft and other hyperscalers
The Commission’s probe places Microsoft and AWS in a delicate public position. Even absent a finding of wrongdoing, the process imposes regulatory scrutiny that can influence customer procurement decisions and shape enterprise contracts. For Microsoft, the reputational risk is paired with the immediate potential of regulatory interventions that could require product and contract changes.For the broader market, the investigation may catalyse:
- Increased customer demand for multi‑cloud portability solutions.
- Greater interest in open standards and third‑party migration tooling.
- Pressure on cloud vendors to simplify licensing and exit clauses.
What customers and IT decision-makers should do now
- Prioritise portability and exit planning — treat contractual exit terms and migration tests as a procurement priority.
- Audit licensing exposure — quantify the cost of running critical workloads across alternative cloud providers, including any non-obvious fees or technical compromises.
- Push for contract transparency — require clear terms for updates, interoperability, and data export formats.
- Invest in multi‑cloud tooling — consider abstraction layers and containerisation strategies that reduce dependence on provider-specific services.
Likely scenarios and timeline
- Short term (weeks–3 months): intense evidence gathering by the Commission; information requests to Microsoft, AWS, Google, and major customers. Google will likely submit detailed evidence supporting their claims while Microsoft mounts a legal and technical defence.
- Medium term (3–12 months): the Commission may issue preliminary findings and possible behavioural or technical recommendations; if gatekeeper designation is considered, that process could extend and be legally contested.
- Long term (12+ months): one of several outcomes — tailored remedies, DMA-style obligations, or no action if evidence is insufficient. Any remedies could face legal challenges and require careful implementation to avoid negative side effects.
Critical analysis: strengths and weaknesses of each party’s position
- Google’s position is strategically strong in that it reframes the dispute as a systemic problem requiring systemic remedies. That strengthens its policy argument and concentrates regulatory firepower in Brussels. The risk for Google is that the DMA process is complex and uncertain; a failure to persuade the Commission leaves Google without the bespoke relief it sought.
- Microsoft’s defence is that the cloud market remains competitive and that its commercial arrangements were negotiated with customers or addressed via settlements where appropriate. Legally, Microsoft benefits from the burden of proof the Commission must meet to show DMA obligations are warranted, but reputational and operational costs are unavoidable.
- The Commission’s approach — using the DMA to probe cloud markets — is a policy lever with significant potential to rebalance market dynamics. That potential comes with high technical requirements and legal risk; regulators will need to be precise in any remedy design to withstand legal scrutiny and to avoid imposing unrealistic technical burdens.
Conclusion — a turning point in cloud competition policy
Google’s withdrawal of its EU antitrust complaint against Microsoft should not be read as the end of the dispute; it is instead a strategic pivot that places the Commission’s DMA investigations at the centre of a battle over how the cloud economy will be governed. The stakes are high: potential DMA remedies could reshape licensing practices, portability norms, and the technical architecture of competition among hyperscalers. For enterprise customers and IT planners, the immediate imperative is pragmatic: harden exit plans, demand contractual clarity, and track regulatory developments closely. For Microsoft and other cloud providers, the probe represents a period of heightened scrutiny where technical details and contractual language will be dissected and may determine the future rules of engagement for cloud competition. The coming months will reveal whether Brussels can translate DMA power into precise, technically informed remedies that foster open, competitive cloud markets without unintended collateral damage.Quick reference — key facts at a glance
