How do you propose that Apple could give this option to Epic?
If they allowed Epic to skirt their rules, they'd have to do the same for everyone, so it is a fight that Epic picked and Apple is choosing not to continue that fight, that's all. You make it sound like it would have been just fine if Apple let Epic do what they were doing.
We can debate that Apple should change its rules for everyone, but it sounds like you think they should have just let Epic continue violating their policies.
Er... yes?

Apple is already allowing Amazon to "skirt their rules".
Would Apple likely have to forfeit more exceptions to other companies if they did this? Probably yes.
Still Apple's decision.
