I, for one, keep choosing iPhone exactly for this reason - I want only apple to control the app review process.
Without this, you’d have every single major company pishing their own installers with a ton of crapware on top of them.
To give an example - Epic on Windows requires you to install their own store, with their own update system and notifications, plus ads showing each time you open up their game.
I don’t want this on my phone - battery aside, I want the device to be 100% secure, and such crapware has a poor track record of security.
I’m really for strong antitrust laws - Google and Facebook are monopolosts who abuse their position. But in case of the phones, both users and devs have a choice - they can use either Apple or Google. Unless both companies are guilty of the same thing (and in this case they are not), how this is an issue?
