EU regulators stepped up enforcement last year and this month, opening a Google probe and levying major fines after the USTR posted on X warning the United States would respond to what it called "a continuing course of discriminatory and harassing lawsuits, taxes, fines, and directives" against U.S. service providers.Key actions in 2025 include a formal Google investigation into use of publishers' content for AI, a €2.95 billion fine for Google in September, a requirement that Meta offer EU users a choice on personalised ads from January, and a €120 million DSA fine on X after a two-year probe.The USTR named Accenture, Amadeus, Capgemini, DHL, Mistral, Publicis, SAP, Siemens and Spotify and warned of possible fees or service restrictions, while the European Commission said rules apply equally and will continue to be enforced.
