alt Hacker NewsAndroid is still developed by google, yes.
The chinese are mostly adding skins on top, not developing the core of the operating system.
There is however a chinese fork of android (state sponsored), but it has not gotten wide market adoption in china either to my knowledge, but i dont live in china so i'm open to be corrected.
Finally, even if that OS has gotten widely adopted in china - it IS a fork. the changes are not being upstreamed to android, hence irrelevant to the discussion on this forum.
I'm talking about the Google services which is where Google profits. Chinese phones ship without them. When I said "Google's Android", I meant Android+Google Services. The people buying cheap Android phones are most likely not buying Pixels. Even Samsungs aren't exactly cheap anymore. I'm not talking about Android forks. I'm talking about customized Android without Google services.
The biggest Android market (internationally) are Chinese phones. If Google suddenly decided Play Store should be the only way to install apps, that doesn't affect Huawei and Xiaomi phones at all, they don't ship with Play Store and Play Services in the first place.
