It's like with politics - you vote for the polarizing person that would eat the other ones so that there can't be a lasting consensus disadvantaging some group permanently. Politicians need to be at each other's throats and never sure about anything to minimize the damage they would do otherwise.
So if Epic wins, will Epic be able to stop other stores from coming up? In what scenario do you see US (you, me, we) winning? The one where Epic loses or one where it wins?
Well, Epic pulls games from other stores and they make exclusive deals, so yes, they actually can stop other stores from coming up through indirect means.
