I assume the same requirements will also apply to Xbox, Switch and PlayStation?
There's a few things wrong with this argument. Despite Apple's attempts to sway opinions otherwise, the iPhone and iPad are both general purpose computers. These are not specialized devices that are meant for specific functions. These are devices that are designed to run a whole variety of apps that can do everything from your online banking to using LiDAR to scan and create 3D models. These are every bit as much of a general purpose computer as a Windows PC or a Mac. Apple can't even use that argument with the iPad seeing as how they advertise it as a laptop/computer replacement.
When it comes to game consoles, the argument fails for different reasons. Sure you can buy your games from their own stores. But if a game is too expensive for your liking on the eShop, Xbox Store, or Playstation Store? Go check Best Buy, Walmart, Target, GameStop, Amazon, local game stores, pawn shops, I've even seen games in CVS, Walgreens, Big Lots, and Bass Pro Shops. The point is, if you want a game on a console, you have dozens of ways of acquiring said game. If I want an app on my iPhone, I only have one place to get it. And, again, game consoles ARE in fact devices designed for just a couple of tasks. They are not general purpose computers...
.. Except Microsoft DOES allow "side loading" on the Xbox. For a small one time fee you can join the developer program and side load any UWP app you like.
I have an M1 iPad Pro that is insanely fast. Same for my iPhone 13 Pro Max. The hardware is incredible. But the restrictions Apple imposes are maddening. There's no reason for it. Especially now that Macs run on the same hardware. It's purely software restriction by Apple to protect their profits. I bought and paid for my hardware, I should be able to do as I see fit with it as long as it is not illegal or harmful to others.
