LONDON (AP) — Apple and Google aren't giving consumers a genuine choice of mobile web browsers, a British watchdog said Friday in a report that recommends they face an investigation under new U.K. digital rules taking effect next year. The Competition and Markets Authority took aim at Apple, saying the iPhone maker's tactics hold back innovation by stopping rivals from giving users new features like faster webpage loading. Apple does this by restricting progressive web apps, which don't need to be downloaded from an app store and aren't subject to app store commissions, the report said.
