Google warns EU antitrust rules risk user data privacy

Regulators in the European Union plan to force Google to share granular search data with rivals and open Android's AI integration to other models. These proposed rules aim to dismantle the company's search monopoly. Google argues that granting third-party AI services the same system-level access as Gemini would expose users to fraud and malicious software.

Privacy concerns center on the sharing of anonymized search data, including click rates and rankings. Google claims its internal teams can unmask individual identities from this data using linkage attacks in as little as two hours. This makes the data highly vulnerable if smaller, less secure firms become targets for hackers after receiving these datasets.

This dispute stems from the Digital Markets Act, which labels tech giants as gatekeepers to prevent unfair market dominance. While Google claims the risks are genuine, critics suggest the company is simply protecting its 90 percent search market share. The European Commission will issue a legally binding decision on these requirements by July 27.

These rules would force a shift in how Android handles system-level AI and data portability. The conflict pits the EU's desire for competition against the technical difficulty of ensuring true data anonymity. The final ruling will determine if competitors gain access to the core data driving Google's search dominance.
