I'm not smart enough to know whether Google is breaking antitrust rules or not but if they are I don't see how Apple aren't too.
The idea being that forcing these additional apps, just to get Play Store is anti-competitive. I'm not sure I'd agree, but there's an argument to be had at least.
It's possible Apple could be too, but they've not used this to try to break into as many industries as Google has AFAIK.
If you want Google Android on one phone you can't ship another model with AOSP version.
