> This move means the end of an enforced, curated walled garden for iOS.
Great! (Imagine having wallgardened Windows computer where you could not install whatever you want).
> This will mean a race to the bottom for iPad apps. Which, of course, means even more ads
iOS store is already at the bottom. Everything is with ads or subscription based. More ads won’t scare me because I won’t use app with any ads. If app offers one time purchase - I’ll buy it if I like it. Examples of apps I bought: Structured, Bobby, ArtStudio, MusicStudio.
> if I want to install things outside the walled garden, I use a my Mac not a mobile device
What if Apple decided you cannot install apps outdide off their App Store on a Mac neither? What would your “Apple-defending” argument be then? It’s NOT a far fetched idea. Microsoft tries it with Windows S Mode and they currently constantly threaten people when they download software from internet about how dangerous it may be, trying to scare people into using their store.
