Yeah, from apple’s perspective it cheapens their brand and makes them just another commodity parts supplier. Plus, used outside of their ecosystem, the cups might not shine the way they do on their managed platform which could tarnish the image too. Plus, it kills some of the competitive edge they have on hardware if anyone could slap something together with the same chips.
I suspect keeping their chips and tech to themselves is vital to their strategy.
My understanding is that only some games are a “key in a cartridge” and they are able to be resold second hand.
