Google said its Android mobile operating system gave users a greater choice of apps and app stores than any other mobile platform. "It also enables developers to choose the browser engine they want, and has been the launchpad for millions of apps," a spokesperson said. "We're committed to building thriving, open platforms that empower consumers and help developers build successful businesses." Apple said it would "constructively" engage with the CMA to explain how its approach "promotes competition and choice, while ensuring consumers' privacy and security are protected." U.S. tech giants, including Google's owner Alphabet and Apple, are drawing increasing attention from competition regulators in Brussels, London and elsewhere.
