At least in terms of their banning xCloud, they recently filed a patent to make their own cloud gaming service. I would definitely say that sounds anti-competitive to ban competitors that are ahead of you from your store, so you have time to make your own.
It depends on the reason for banning xCloud and if their product becomes market dominant. The rules are there. It seems unfair to punish Apple for someone else breaking an agreement.
Ah, so the key to a monopolistic company being a monopoly is that we have to wait for them to become a monopoly elsewhere, after they've banned their own competitors from the space they just entered/want to enter. Makes sense.
