Of course there is. Mobile OEMs are quite capable of making their own operating systems and not so many years ago they all did. Of course Apple does, and Samsung still does with Tizen, from what I know.
These alternatives mostly suck but "your competitors suck" is not grounds for an anti-trust violation. No phone vendor is forced to deal with Google, that's an absurd distortion of the facts. Even if they feel their own in-house engineering abilities are so weak they can't make a better platform than Android, they can still take the open source code and use it as a base, providing their own mapping and app store along the way ... just like Apple do.
