And the non-malicious explanation for that is simple. The majority of the million apps in the app store are small fry to them, and they can't scale support to that level in any empathetic rational manner.
My wishlist for legislation is:
1/ Apple has to allow side loading of apps (make it an advanced developer setting, with plenty of warnings and periodic reminders, that's fine).
2/ Apple cannot force usage of Apple pay and apple sign in.
3/ Apple cannot force developers to hide any options or even information about alternative mechanisms to pay for content, or sign up to a service.
