So here is the question(s).
1) Is Apple charging too much (30% for the first year i believe, 15% every year after)?
2) Who should pay for Apple setting up the store, maintaining it, securing it, and making it so easy to use?
3) If there is no Apple Store, would you still use an iOS device?
4) Would you as customer trust any other competing "app" store on your iOS device?
5) If developers are right, how come there are so many apps on the app store?
6) If the developers are right, why not stop developing on Apples platform?
Every store has to make money, be it retail or virtual. They all sell products that they have to make money on (Markup) in order to provide that store to the customers. Everything that goes into it is maintained by the owners of the store. The merchandise that is in the store costs the owner money to buy. They make money by reselling it AND marking it up by whatever they see fit (what the market will bare). This is NORMAL. If you want to make your own store, you can go ahead and do so. But Apple WILL NOT LET YOU PUT YOUR APP ON THEIR DEVICES. Because they are not going to deal with YOUR BS when things go badly. This isn't hard to understand. Money is part of it, of course. BUT, Apple 100% prides itself in controlling the ENTIRE experience on the iOS devices.
When Apple moves all products to Apple Silicon. Then sell that same app via the Mac side how every you like.
