German email service Tuta Mail has complained to European Union tech regulators about what it described as a sudden drop in Google search results on the day the bloc's new tech rules kicked in. The European Commission last month launched investigations into Alphabet unit Google, Apple and Meta Platforms over potential breaches of the new Digital Markets Act (DMA), with Google's case partly focused on whether search results discriminate against third-party services. Tuta Mail, which says it is the second-largest encrypted email service in the world with more than 10 million users, filed a complaint to the DMA taskforce on Tuesday.
