Dude, WHAT. This is totally against what Linux and Open source in general stand for.
I don't support the thing that I'm sure was their reason for this but I definitely don't support banning someone from contributing to an open system solely off nationality.
So what eventually only the "good guys" can contribute to and use open source software? Who exactly decides who the "good guys" are in this scenario? USA? China?
The implications of what this can cause in the future for potentially all of the open source community is absolutely sad. We should welcome all our fellow human beings to contributing to open source.
Reminds me of a comment the other day on a post about Ventoy. Whatever the situation there is, which definitely needs clarification still, the person was saying that you shouldn't trust it at all because the maintainer is Chinese, even though he has emigrated away. Because the CCP will be able to leverage his family still there to force him to create a backdoor.
I knew a (asian) guy who was working for a government contractor serving the US military. The racism is very serious to say the least. He got framed when something went down and was almost tried with treason. (that carries the death penalty) The authorities hit him with questions about his loyalty to the US for 5 hours even though he grew up in the US and so did his parents.
