At Meta, 90% of my coworkers were Chinese (twitter.com)

Really? In china?

Was this deliberate? I don't think so. Was it?

the 90% claim is believable - I find his other claims to be exaggerated and unlikely

Dude, you work at Facebook, and you're surprised and/or expect us to be outraged to discover that it is a toxic workplace. Surprise! The work culture at a company that is an active driver of intentional enshittification of human culture since literally the whole time, is terrible. Do yourself a favor and quit. or do the rest of the world a favor and rm -rf / the whole stack.

That is quite surprising. While at Huawei (European lab), my coworkers were very diverse, with Chinese being a minority. And even when the higher ups were not fluent in English, and despite me being halfway decent at Mandarin, we still only ever spoke English.

At the same time, there is the saying of "中国人不骗中国人" amongst scammers I've encountered. I wouldn't be surprised if they favored their own in Meta
