Italy Investigates Microsoft for Raising M365 Price with AI

What Happened?

On June 26, 2025, Italy's Autorità Garante della Concorrenza e del Mercato (AGCM) announced a formal investigation into Microsoft for possible abusive practices related to the integration of its AI assistant Copilot into Microsoft 365. According to the regulator, Microsoft allegedly modified subscription terms so that existing users were automatically migrated to more expensive plans including Copilot, unless they took explicit action to opt out. The AGCM argues that this practice was not communicated clearly and promptly, potentially violating consumer protection and unfair competition rules.

Why Is This Important?

This case is significant for several reasons. First, Microsoft 365 is an essential tool for millions of businesses and individuals in Italy and worldwide. Any change in its pricing model affects a massive user base. Second, the investigation addresses a key issue in the AI era: can tech companies force users to pay for AI features they did not request? Third, Italy is often a precursor in European tech regulation; its stance could influence other EU countries.

Moreover, the case highlights the tension between innovation and consumer protection. Microsoft argues that Copilot adds value, but the regulator questions whether users were adequately informed and had a real choice. The mechanics of the price increase—how it is communicated and implemented—are as important as the price itself.

Potential Consequences

If the investigation concludes that Microsoft violated the law, consequences could include significant fines (up to 10% of global annual turnover) and an obligation to change its business practices. This could involve offering users the option to keep their previous plan without Copilot at a lower price, or changing how AI integration is communicated in the future.

On a broader level, this case could set a precedent for other software companies integrating AI features into their products. Google, Adobe, Salesforce, and others are also adding AI capabilities to their subscriptions, and regulators will watch closely how they manage the transition. If Italy sanctions Microsoft, it could encourage other competition authorities to act similarly.

What Should Readers Know?

• Current Microsoft 365 users in Italy: Review your invoices and check if you have been migrated to a more expensive plan. You have the right to request clear information about the changes and, if desired, opt for a plan without Copilot.
• Businesses: Assess the impact on your IT budget. If you use Microsoft 365 at scale, the cost increase can be significant. Consider negotiating with Microsoft or exploring alternatives.
• Users outside Italy: Although the investigation is Italian, Microsoft might extend global changes to avoid regulatory conflicts in other countries. Stay alert for possible modifications to your contracts.
• For everyone: This case is a reminder that AI integration into existing products is not always transparent. Always read the fine print and question automatic subscription changes.

Historical Context

This is not the first time Microsoft has faced antitrust actions in Europe. In 2004, the European Commission fined Microsoft for abusing its dominant position with Windows Media Player. In 2013, it received another fine for failing to comply with browser choice obligations. This new case fits into a long tradition of regulatory scrutiny of Microsoft, but with a novel focus: AI monetization.

The Italian investigation also comes at a time when the EU is developing the AI Act, which will regulate artificial intelligence systems. Although this law does not directly cover commercial practices, it does establish transparency requirements that could complement competition authority actions.

Technical Analysis

From a technical standpoint, integrating Copilot into Microsoft 365 is not trivial. Copilot uses large language models (LLMs) that require costly cloud infrastructure. Microsoft argues that the price increase reflects added value and additional costs. However, the regulator questions whether users were informed that upgrading their plan meant agreeing to share data with AI systems, raising privacy concerns.

Furthermore, automatic migration to more expensive plans can be considered an 'opt-out' practice rather than 'opt-in,' which is generally seen as less respectful of consumer autonomy. The AGCM argues that users should have had the option to actively choose whether to pay for Copilot.

What to Expect Next

The investigation is in its early stages. Microsoft now has the opportunity to present its arguments and offer solutions. The company may voluntarily modify its practices to avoid a penalty. If the case reaches an adverse resolution, there could be appeals and lengthy legal proceedings.

Meanwhile, users and competitors are watching closely. The outcome could define how software companies integrate AI into their products without engaging in anticompetitive practices. For the industry, this is a crucial moment balancing innovation with consumer protection.
