Yeah, yeah, it's Chinese government propaganda, but isn't all advertisement basically propaganda? "Everything is rosy in Xinjiang" is a harmful lie, but so is "if you buy a big-ass truck you'll be a manly man" and frankly I think the latter is causing a lot more damage because it's one that people act on.
This is textbook phase one of what Cory Doctorow calls "enshittification". Users don't have much of a choice, so make it as shitty as you are able without them leaving? Check. Phase two (which Google is no doubt also doing) is to do give the same treatment to the advertisers.
The pressure to maximize profits ensures that all private entities performing this sort of connection role on the internet will eventually become enshittified. There's no escape (under capitalism).
