Vast amount? Gonna need some source on that one
I mean, all developers want to make more money… there is nothing really surprising about that.
The real issue here is Apple doesn’t really make games. Epic does. So epic can go setup a store for themselves where they charge whatever fees they want… or no fees at all. They then make more money on their games and as long as they don’t mind footing the bill to run the store for others, they can force Apple to take a smaller cut, but unless Apple simply stops charging fees, they will never have a reason to go back.
Epic most definitely doesn’t actually care about any other developers success regardless of whatever they may claim.
Much like Apple can run ATV+ and Apple Music at a loss to entice customers, so too can epic run a store at a loss. So they can always undercut Apple. Epic won’t care either way because all they want is their micro transactions to pay out 100%.
Where this becomes a problem is Epic doesn’t care nor have a vested interest in maintaining the performance of your device, it’s security, etc. They would be just as happy if you ditched Apple and for an android as long as you kept giving them money for their games. So if they make Apple look bad, they don’t need to care. If they damage Apple devices reputation, they don’t need to care. Etc.
Which is why the DMA will probably allow the core tech fees to stay and Apple will continue to do everything they can to make using the 3rd party stores inconvenient and painful. Not only are they worried about the loss of App Store revenue, but market share and hardware revenue as well if such stores can make their devices irrelevant.
I think it may well come down to a game of chicken between stores on who’s willing to eat a bigger loss and probably some degree of fragmentation. There is absolutely no chance of the store fees going away entirely as running them does cost money both for servers/storage AND credit processing fees. DMA may be made to protect consumers, but it’s also quite anti business, at least if they rule fees imposed on the 3rd party stores a violation. Since why would Apple bother making devices if another App Store became more successful and they dropped making money on anything but hardware.
