Because you use steam and the play store and ... to get games, and there will be so overwhelmingly much slop you can't find anything.
I've switched to emulators, a bluetooth controller and zero android games (and zero ios games on my work phone). But yeah it was/is horribly enshittified already. And what people predicted did happen.
The fact that the app store allows updates means existing games get systematically worse. Even the games I used to enjoy, and bought 5 years ago, like collossatron now have ads after every play.
