>YouTube would face riots if it were caught openly supressing or hiding videos of disabled, unattractive, or simply poor people. But such "innovation" is fine for a Chinese company.

You don't need an algorithm to hide unattractive people. Ever seen a modern TV show or a casting contest or seen the latest comic adaption in cinema? People voting out the unattractive or even unconventionally attractive is an old story, the more mainstream the content the more the stars look like models. On Youtube it happens with Likes and on TikTok it happens through some ML magic, I guess in China there's no fucks given about actually baking it into the algorithm directly but that's hardly more than a technical detail
