When they say "Worst Fears [...] Were Just confirmed" they are at best misleading.
There has been a notable dearth of reporting by traditional journalistic media about this topic, and so I am still somewhat skeptical. The evidence presented so far is not as conclusive as with the Uyghur suppression.
The practice described in the article would undoubtedly be a crime against Humanity, and among the biggest in history. But I can't tell right now if the process of its discovery is just slow-moving or if there is just nothing that big to discover. I'd appreciate any pointers to more information either way.
