"That last point may seem odd in light of Apple’s victory, but again, Apple was offering an integrated product that it fully controlled and customers were fully aware of, and is thus, under U.S. antitrust law, free to set the price of entry however it chooses. Google, on the other hand, “entered into one or more agreements that unreasonably restrained trade” — that quote is from the jury instructions, and is taken directly from the Sherman Act — by which the jurors mean basically all of them: the Google Play Developer Distribution Agreement, investment agreements under the Games Velocity Program (i.e. Project Hug), and Android’s mobile application distribution agreement and revenue share agreements with OEMs, were all ruled illegal.
This goes back to the point I made above: Google’s fundamental legal challenge with Android is that it sought to have its cake and eat it too: it wanted all of the shine of open source and all of the reach and network effects of being a horizontal operating system provider and all of the control and profits of Apple, but the only way to do that was to pretty clearly (in my opinion) violate antitrust law."
The key is 'unreasonably restrained trade' - Any OEM was eligible to use Android, but what google did was restrict competition by 'entered into one or more agreements that unreasonably restrained trade'
