I don’t think Apple decided that. I think people, with their money, decided that.
If one was trying to make the point that, “It’s not because people didn’t buy the games that Capcom hasn’t continued development,” then that’s the kind of thing one would make up. As it is, Apple provided the same level of support that they provide to any developer that’s paid their $99 and the fact is that there’s not enough folks that want to buy and play RE Framework games on iOS/iPadOS/macOS devices to make it work Capcom’s time (if Capcom has no future plans that is. If it’s been profitable, then they may release something months after this was written).
I mean, look at Delta… it’s proof that a lot of the folks interested in this type of gaming is not interested in paying anything more than “free” for it. Free won’t make Capcom very much money at all, and they ARE in business to make money.
