Yes, and for distribution, that's fine.
The ruling is less about Apple forcing consumers to buy only through the AppStore, and more about only allowing sellers to sell through the AppStore.
If I make a PS4 game, or a Nintendo Switch game, I can sell it on the PSN store and/or Nintendo e-Shop, sure, but I can also produce a physical copy that I can obtain outside of the store, and that is definitely not the case for Apple software developers.
Apple software developers MUST go through the AppStore and they MUST pay that fee, no matter what.
It is that specific lack of competition; the lack of other places to sell your iOS applications, that the USSC judged against, by my reading.
