> Indeed, for example, Epic Games has agreed to such a rate on all Fortnite transactions via the Microsoft (Xbox) Store, the PlayStation Store, the Nintendo eShop, and Google Play. Epic Games has also agreed to extra payments for certain platform holders above and beyond the standard 30% commission rate. For example, for all Fortnite transactions via the PlayStation Store, Epic Games agreed to make additional payments to Sony above this commission rate based on the amount of time that PlayStation users play Fortnite cross-platform.
The judge forced Apple to allow transactions to take place off of the platform, but she explicitly noted that Apple would still be entitled to a commission on said sales.
Apple sees their App Store arrangement as similar to Upwork, Rover, or any number of other marketplaces, which all have policies preventing users from meeting through the system but transacting outside of it. From their perspective, if they hooked you up with the sale, then they're entitled to a commission. If you think you can do better without their sales, you're welcome to pull out of their marketplace, and if they find that you're abusing their marketplace they'll hasten you to the door.
That is, as far as the judge was concerned, perfectly legal, and I'm having a hard time not seeing it as a reasonable position to take.
