If you wanted a dedicated streaming device, the competition is much cheaper.

But sure, nothing on a technical lecdl stops you from using a console as a general computer. It's just that that's not what the overwhelming use is as of now. Use cases play a large factor in rulings like this.

Well, its not just "games vs phones". The question is whether or not the company's actions unfairly stifle competition. Nintendo / sony / etc would argue there's lots of competition, because you can just buy their competitor's product if you think they provide a better service. The argument is weaker for apple because its much harder for regular people to "just" swap their phone between ios / android over differences in the app stores.

Consoles compete on games. Phones compete on specs, and then they happen to have an app store on the side. Thats a difference.
