I'm confused at how this is any different than how both android and ios embed siri and google assistant in over allowing other assistants to compete, or what about the fact that you need to log in with an apple/google account to really use the platforms in any meaningful way (for at least most android distributions). Part of me wonders if the EU just has a problem with google, as they have charged them time and time again, when other platforms engaging in anti-competitive practices get away with it.
