Not completely, but maybe enough to lower the insane fees?

For instance, why not charge for the services used and a low payment processing fee? If developers bring associated costs, they should pay for it. It just seems 30% is overshooting quite a bit. They want to treat developers like regular customers with regular margins, when they are more like partners bringing them nearly free revenue.

I guess I'm too ignorant to understand how building, maintaining and securing the App Store is 10x more expensive than doing the same for something like Mastercard.
