You're basing your statements on a very narrow and limited use case r/PCMasterRace & not how
over a billion iPhone users use them.
Apple did not become a
nearly $3 trillion company by catering to frictionless parts replacement market that dominates PC gamers.
Triple A titles have comparably small revenues than the App Store. It only matters to you because their marketing is very effective on you.
Apple has shipped more iPhones & iPads than the whole Intel/AMD PC industry combined. Apple is not wanting for revenue.
They let others cater to that frictionless parts replacement PC market as it is too expensive & bothersome to cater in the same way that Apple decided to let others cater to the sub-$999 desktop/laptop market, sub-$399 smartphone market and the sub-$329 tablet market.
As pointed out by
sunny5 gaming revenue favors smartphones/tablets & and not Windows anymore.
Apple can easily ignore your gaming interests because the net plus to them is not worth their time. Let small time companies like Intel/AMD/Nvidia cater to it. Hell, they should be thankful Apple aint interested or they'd lose their shirts.
