Google draws scrutiny from antitrust regulators in regard to phone software because Google is separate from the phone makers.

What if pixel phones become the only way to use Android?
These are just semi-rhetorical (and unlikely scenarios) questions.
Yes, why not? Or that rule only applies to Google?
With Apple the OS maker, the store maker, and the phone maker are all the same entity so it doesn't even make sense to say that the OS vendor is trying to force their store on the phone vendor.
If Apple draws antitrust scrutiny, it will be for something different that what is drawing attention to Google, such as for not letting third party stores on their phone.
