ACCC Sues Microsoft Over Misleading Copilot M365 Subscriptions
Published: 3 Nov 2025 | By Aurzon Insights
Australia’s consumer regulator has launched landmark proceedings against Microsoft, accusing the company of misleading millions of Microsoft 365 subscribers by bundling in its AI assistant Copilot and concealing cheaper alternatives.
What’s Happening?
The Australian Competition and Consumer Commission (ACCC) has filed court proceedings in the Australian Federal Court against Microsoft Australia Pty Ltd and its parent, Microsoft Corporation, alleging that roughly **2.7 million** Australian consumers of Microsoft 365 Personal and Family plans were misled into upgraded subscriptions. :contentReference[oaicite:6]{index=6}
The case centres around Microsoft’s integration of its AI assistant Copilot into its Microsoft 365 plans (Personal and Family) from 31 October 2024, and the accompanying price hikes. The ACCC alleges that Microsoft told subscribers they *must* accept the new Copilot-enabled plan and pay more, or cancel their subscription. However, there was allegedly a third option—retain the existing plan without Copilot at the lower price—that Microsoft failed to adequately disclose. :contentReference[oaicite:7]{index=7}
Key Allegations
- Microsoft’s communications to subscribers wholly or implicitly conveyed that the only choice was: upgrade to Copilot-integrated plan at higher cost, or cancel the subscription. :contentReference[oaicite:8]{index=8}
- A “Classic” version of Microsoft 365 (without Copilot) at the previous lower price apparently existed—but was disclosed only through the cancellation flow (i.e., after users began canceling) and not in the initial renewal/up-sell communications. :contentReference[oaicite:9]{index=9}
- The annual subscription price for Microsoft 365 Personal allegedly increased by ~45 % (from A$109 to A$159) and for the Family plan by ~29 % (from A$139 to A$179) in Australia after the launch of the Copilot integration. :contentReference[oaicite:10]{index=10}
- The ACCC claims this conduct may breach the Australian Consumer Law (ACL) by failing to provide accurate information about pricing and options, thus depriving consumers of informed choice. :contentReference[oaicite:12]{index=12}
Quotes from the Regulator
“Following a detailed investigation, we will allege in Court that Microsoft deliberately omitted reference to the Classic plans in its communications and concealed their existence until after subscribers initiated the cancellation process to increase the number of consumers on more expensive Copilot-integrated plans.” – Gina Cass-Gottlieb, ACCC Chair :contentReference[oaicite:13]{index=13}
“We’re concerned that Microsoft’s communications denied its customers the opportunity to make informed decisions about their subscription options…” – Gina Cass-Gottlieb :contentReference[oaicite:14]{index=14}
Why It Matters
The case is significant for several reasons:
- It highlights how large-scale software subscription models and AI integrations are under regulatory scrutiny globally for fairness and transparency.
- It may set precedent for how bundling of AI services (like Copilot) with existing subscriptions is handled and disclosed to consumers.
- For consumers: the dispute raises awareness to check whether cheaper “legacy” or “classic” versions remain available when upgrades are introduced.
- For businesses: the case underscores the importance of clear communication when altering pricing, bundling, or auto-renewing models especially in nations with strong consumer-protection regimes.
What Microsoft Says
Microsoft has acknowledged the ACCC’s action and said it is “reviewing the ACCC’s claim in detail”. :contentReference[oaicite:15]{index=15} The company has stressed that “consumer trust and transparency are top priorities for Microsoft.”
However, Microsoft has yet to publicly confirm how it will address the alleged conduct in Australia, or whether any compensation or remediation will be offered to affected users. The legal process is ongoing.
Potential Outcomes & Timeline
The ACCC is seeking a range of orders against Microsoft, including:
- Penalties (which under the Australian regime can be substantial — e.g., up to the greater of A$50 million, three times the benefit obtained, or 30% of the adjusted turnover of the corporation for the breach period). :contentReference[oaicite:16]{index=16}
- Injunctions to stop the alleged conduct.
- Declarations of contravention of consumer law.
- Consumer redress (refunds or compensation) for affected subscribers. :contentReference[oaicite:17]{index=17}
Given the ACCC’s public statements and the major scale of the alleged conduct (2.7 million users), the case may take many months (or longer) to resolve. Both the regulator and Microsoft will likely negotiate or litigate in the Federal Court of Australia.
What This Means for Indian Consumers & Businesses
While this case is Australia-specific, it carries lessons for India and other markets:
- Indian consumers of Microsoft 365 should review their subscription plan and renewal communications: Was a lower-cost plan without bundled AI options clearly offered?
- Indian businesses reselling software or advising clients should ensure transparency around AI-feature bundling, pricing changes and renewal terms — especially where auto-renewals apply.
- Globally, as AI features become more common, regulators (in India: Competition Commission of India, consumer protection authorities, data bodies) may examine similar practices and require clearer disclosures.
Aurzon will continue following this case and bring updates relevant to Indian audiences and subscription software users.
