I don’t disagree with that. But equally most business units in Apple are not tied to revenue streams. From R&D though to developers for other non-subscription software. And that’s before you then factor in the non-delivery team (eg finance, HR, lawyers, etc).

So it’s not like a review stream is a requirement.

Moreover, even back when they did have back office tooling as a revenue stream (eg OSX Server), Apple still left it to slowly rot before finally discontinuing it.

So I just don’t think this is something anyone’s Apple cares enough about. If they did, then we wouldn’t be having this conversation to begin with.
