Developed at Berkeley by Yangqing Jia, a Chinese national.

A Chinese national whose project was backed with US public funds. Triple irony.

There are (many) more Chinese nobel prize winners who won them for work in the USA than in China. It doesn’t sound like irony.

A large portion of US inventions were made by people of different nationals, I don't see the irony here but only narrow-mindedness.

I'm not objecting to foreign nationals doing publicly funded research in the US. And I was not the first to bring up his nationality. Personally, I don't care what his nationality is. The initial irony I noted was that a US university had produced an open source project that is the chief tool of face detection on the mainland.

I don't get the irony. Does nationality matter for open source project with a clear license?

double irony rainbow!
