One proposal for a compromise that would feel fair: Apple gets 30% of the app creator’s take rate.
IE if patreon’s take rate is 8%, Apple should get 30% of that, not 30% of the full transaction. This could generalize to physical goods as well. It would require more reporting, but would feel more fair in the eyes of the creators and the users.
I run a similar service to patreon where I charge a flat $1 fee on subscriptions, regardless of the size of the subscription. A $50 sub suddenly getting only $34 after my $1 fee and apple’s $15 fee feels wrong. There’s no amount I can reduce my take rate to cover Apple’s take. But I’m entirely ok giving them $0.30 on my $1 take.
Basically - I’m entirely OK having 30% of my net profits taken by Apple. I’m not ok with 30% of my gross.
