Did you see any proof showing there is concentration camp in Xinjiang? Or you just read it from news and have you doubted whether the news is fake or not?
Thousands? Pretty much every article that I have read about concentration camps, I have tracked down to unreliable sources like CIA-funded propaganda organizations.
I don't see articles from amnesty international going viral in western media. The last big China bad news story in HN was [1], which was literally funded and assisted by a CIA-funded organization. An article which uses a few blank spots in a map to make up just crazy conclusions?? And people in HN just seem to buy it without any of the usual skepticism you see HN show about the most boring science articles showing the most obvious results. It's like that in pretty much any western social media site. Makes you think you're living in some alternate reality.
