WeChat is owned by the 'private company' Tencent. And most here think it's perfectly valid when Facebook or Google censor things they don't like. I'm sure you think that Google is a real private company, while Tencent is not. But the difference isn't really all that valid anymore; the US government has backdoors and special access to our tech behemoths, just like the Chinese do for their tech companies.

Maybe it's not such a good idea to cheer for Google, Facebook, and the other companies when they censor whatever it is you currently dislike politically. Do you naively believe they'll not someday censor you, too?
