With all the control they have on the App Store (and they have showed they are perfectly fine using it when it suits them) arguing about privacy is pure virtue signaling when they allow Facebook and Google just fine. And most of their core services/apps could actually work mostly fine in a web browser so it's not like there would absolutely no way to use them. They could very much have strict requirement on data tracking and basically forbid any app doing it and that would actually make the "managed App Store" pretty good. But they don't, because they would lose a shit ton of money in various ways.

But Apple wants the cake and eats it too. They can't pretend to have principle and just throw them away when it hurts their profit. That's no standard at all but that's how it is. Apple makes pretty good technology but is completely full of shit and I would argue much more than the other usual suspects and that makes them the worse guy actually.
