I understand Apple's decision to do this. They want to stick it to Epic. Completely understandable desire on Apple's part. But, sadly, Apple is letting their desire to get vengeance outweigh the interests of their users in having all the games they want to play on their devices. I have been realizing lately that my loyalty to Apple has been waning over the years after having invested heavily in the ecosystem. This is…
Post-NeXT (or at least post-iPod) Apple has always been about total control of user experience, not letting users do all of whatever category of activity> that they want.
I don't think that vengeance is necessary to explain this.
