It kind of is like rent seeking though. Apple has developed a product with some software but not the software we call Fortnite. They are now acting similar to a company like ExpressScripts, who created an organization in the form of a platform so they could extract rents from both the drug makers and the (insurance company) buyers. If Epic keeps the game off iPhone, there’s some overall loss to consumers. If they keep prices the same but pay the Apple fees, they pay rent to Apple. If they raise prices across the board to compensate, consumers pay rent to Apple and there is some deadweight loss because of a likely reduction in demand.
