Ben always writes interesting analyses and I think this article is worth reading if you want to understand what is going on between Apple and Epic Games. There is no doubt in my mind that all the pressure Apple is under will lead to some changes in their App Store policies, which is a good thing for developers and also users.
Epic is attacking every level of the iPhone stack: the company doesn’t just want a direct relationship with customers, and it doesn’t just want to use its own payment processor; it is also demanding the right to run its own App Store.
