I don't know what the op is referring to but just a guess. I know one app, HelloTalk where I think you can get paid to teach language. Think of it as zoom + twitch but centered around language learning. You can run a channel (twitch style) and you can take private "zoom" calls for money. Apple is probably taking 30% for those calls.
You don't need to do radical changes, just small actions like do not steal the tips students send to teachers.
Going full-goblin mode and demanding 30% of all the money that moves through a phone is what is destroying Apple.
