Read the case, the whole thing started because Google banned Epic from the Play store, and the only reason for it to become a case, was the monopolistic position. That’s gone now, they’re free to refuse service to whoever they want, whenever they want, for no reason at all… and if you don’t agree, go sue them, they’ll show you the precedent followed by the door.
By adding support for alternate stores, the monopoly argument is gone: everyone can build their own store now. Meaning, everyone with a store can kick out anyone else, and tell them to just build their own.
…which they can change at any moment, but don’t really need to; most ToS include clauses about refusing service without having to explain why. If you ever agree to a ToS, better make sure they’re even supposed to notify you if they ever decide to cut you off.
