Sacrificing freedom & rights for user experience and comfort, that's how we get dictatorships. Apple takes total control but we shouldn't worry because they are "the good guys" acting "on user behalf" ?
We have to distinguish User Experience (short term comfort) from User Respect/Freedom/Rights. Choice is bad for UX, but it is good for avoiding abuses.
If you download FB, Instagram, TikTok, etc. on the app store those are malwares that collect all your data and Apple is doing absolutely nothing about it. ICloud is not even end-to-end encrypted. Let's stop this myth that Apple provides actual privacy.
Apple doesn't care about you, they care about power.
If they need to put "Privacy" in their ads for you to buy it, they'll do it. If they need to keep malwares on the app store to generate revenues, they'll do it (but they'll make sure you believe you are safe thx to their fake privacy propaganda).
It's true other game platforms are closed but first we have more choice :
Mobile gaming = Google or Apple
Home gaming = Nintendo, Xbox, PlayStation, Linux/Windows/Mac, Steam, Itch.io, GameJolt, Windows store, Epic game store, Origin/Ubisoft/Blizzard, etc.
Second : it's not about gaming only, it's about the right of people to control the device they bought.
Iphone & Google have a far bigger monopoly and control on our life than an Xbox sitting in our living room, so it makes sense to worry about Apple and Google first.
