Message : Required fields BRUSSELS (Reuters) - EU antitrust regulators are set to charge iPhone maker Apple this week with blocking rivals on its App Store following a complaint by music streaming service Spotify, a person familiar with the matter said on Tuesday. The move, the first EU antitrust charge against Apple, could lead to a fine as much as 10% of Apple's global revenue and changes in its lucrative business model. Reuters was the first to report about the imminent EU antitrust charge in March. Sweden's Spotify took its grievance to the European Commission in 2019, saying Apple unfairly restricts rivals to its own music steaming service Apple Music.
