Epic would like to proccess these themselves. They dont want apple to turn on their economic output. When you charge money for the work others do -- that's like communism.
This discussion is about Epic charging for in-app things outside of Apple's control. So apple can't use the argument that they have costs (support, payment) for those transactions.
If I buy a hat in the Epic store (and pay to epic) I don’t see why it would be very different.
Should it matter if I make the purchase in Safari or in another app?
Also: let’s forget the apps for a while. Assume I buy a navigation app for $10 on the App Store and then I visit a website and purchase gps maps for 3 countries to use in the app, for $100 each. Apple isn’t involved in that transaction. Should they claim a cut of the $300 because I can use the maps in the app?
