Earlier quoted context omitted.
Epic is the customer here also and they want to be able to provide a convenient and cheaper way for their customers. Their asks are not only reasonable, they are consumer friendly. Apple is just being a bully.
Imagine you want to sell a valuable, consumer friendly product that is cheaper than some alternatives and will save people money, but in this case, in a brick and mortar store. The brick and mortar store says "we agree to stock your product, and will take 30% off the top for our troubles." Would we be saying the same things? It's the same dynamic, in my view.
There are only two chains of brick and mortar store in the world and one with double digit market share (Apple) has decided to take 30% off the top for all goods sold in all of their stores and have banned products from having any indication on their packaging that they can be purchased elsewhere for different pricing. Entering any store also requires an extremely expensive chain-specific device that most people purchase on credit every few years, eliminating the ability to easily shop around at both chains.
If this were to happen outside of tech, the perpetrator would get crushed by anti-monopoly legislation.
