Facebook is not listed on the Chinese App Store, but you can install it easily by switching your region to the USA, installing Facebook, and then switching your region back to China, without losing apps from either region. (I know this because I owned an iPhone while living in China)

Much easier than having to bother with a VPN, and many Chinese people are already used to jumping through such hoops.

China puts up with it for whatever reason, but the US doesn't have to. The US can just as easily order Apple and Google to remove it from every region of every app store.

They can’t actually do that. There are good reasons apples Chinese App Store is run by their Chinese subsidiary. That would be like China ordering Apple to remove Facebook from their American App Store.
