That's a great question! How far does Apple's control extend into markets that are unrelated to their core business? I always prefer using mobile websites on my own android phone instead of downloading apps because of security concerns and general notification spamming, ads, and annoyances, and it seems to me this would be a great solution ie just replacing "apps" with bookmarks. For the current situation, I may look into services like Nebula, doing PayPal directly, YouTube subscriptions and donations, or setting up an online store. Or even.... sponsored videos!! (just kidding)
