Some accountant at Apple is shaking their head. Lose one of the most profitable/high volume items in the inventory just to uphold a theory. The math says shaving a few points off for Epic would still bring in more money than not having the super seller Fortnite at all. Apple may have won the battle, but Epic is playing the long game here, showing other game publishers that their is growing competition to the Apple walled garden store with more attractive returns by using Epic or Steam, or even their own store. All it takes is for a few block busters like Fortnite to train consumers that the Apple store is not the only alternative, and Apple is in deep doo doo.
