That’s like saying Porsche has a monopoly on all red mid-engine German sports coupes. Apps run on pocket computing devices with phone and data connectivity. Two operating systems compete in that space.
No, that's not like that at all. Can we stop making really poor car analogies that don't actually represent the issue at hand?
Regardless, at this point you're arguing against the court here. Google lost; they have a monopoly on Android app distribution. Maybe that'll get overturned on appeal, but I hope not.
