Historically, I think it dates back to Jobs not liking them, Apple doesn't really care about games. It begrudgingly accepts them on the platform as second rate citizens since there's a lot of money involved.
I wonder if they think you either have to be the top dog (PC? PS5?) or you're better off getting the casual gamers (iOS) and not distracting the core business? It's a massive, successful company. I don't think they begrudgingly accept it, or extrapolate from the personal preference of a past boss. The past boss taught them that style and status sells and they've continued with that because it's successful, not just because it was his thing.
