I believe Apple users choose the Apple ecosystem specifically because they value the protection the App Store provides. I can't even imagine the nightmare if every app was allowed to redirect me to their website, register there and enter payment information before I can start using their app. This system would be abused as hell. The in-app purchases are transparent (I can review all my transaction in one single place) and I can approve my child's purchases remotely.

Also I am sure if the roles were switched, Spotify would no way in hell allow Apple Music to be priced the same way on their App Store for their ecosystem users. It's hypocrisy.

I agree 30% might be too much, but it's their App Store, their users, their infrastructure, their public trust at stake, their rules.
