HN is literally banned in China [1][2]. And since VPNs are also illegal in China, they're breaking the law if they are here. I doubt they'd break the law if they had such a strong allegiance to China.

International Steam is also banned in China yet we curiously see the majority of users nowadays use simplified Chinese.
