Features like group chats and image sharing are barely useful on SMS. There is no encryption either. > 57 percent US 30 globally is not a moat, its first mover advantage, and its on a premium product. And if apple had 90%, and still allowed for Signal, and complied with SMS you would be hard pressed to get iMessage access to raise to the levels of the DOJ and anti trust measures. Those are still huge numbers and way more people using their product than microsoft had in the 90s. I don't even think Apple needs to open iMessage, they just need to support RCS (which the EU is forcing them to do), and most complaints will go away.
