The final item is very specific to Unreal Engine so it is clear that this is not simply a template e-mail and was crafted specifically for Epic. Thus we can assume that Apple legal, marketing, the executive team, etc. have pored over every line intently (despite misspelling iPadOS).My guess is that this is intended to enumerate everything that Apple contributes to earn its 30% cut.
Epic themselves have now entered this list into the legal record, claiming that it would be incredibly damaging for them to lose access to these features. Perhaps it is now harder for them to argue that Apple's cut is excessive.
