(It's also amusing to see that sometimes shift when they get their citizenship; I had a Japanese classmate in college who was on first a student visa, then an H1B, then a green card for about 15 years. He had zero political opinions for the whole time I knew him. As soon as he got his citizenship, he's active in local politics. It's more about urban planning, transit, and YIMBY efforts than immigration, though.)
Where the hell are you working? I'm going to call bullshit, because it's really not that easy to get a work visa in the US. You're saying 90% of your colleagues weren't US citizens?
A similar dynamic works on sex, as well. About half of the teams I worked at were roughly 40% women; the other half of them had zero women. Women are generally reluctant to join a team where they will be the only woman, and also word gets around about who the female-friendly managers are. So those female-friendly managers get teams that are close to 50% female, while other managers get teams of zero women. (Statistically, Google Engineering was about 10% female and IIRC 50-60% foreign-born, which means that I encountered about twice as many women that I would've been predicted to and about half as many foreigners. I wonder what that says about my personality.)
Will people please consider a moment's thought before using this adolescent phrase? People throwing it around are probably not using it with its most precise and defensible meaning (a la Harry Frankfurt). So the most charitable alternative gloss is that it's used carelessly to mean someone is just wrong. It's a very poor (because ambiguous) word choice for that. I suspect it's usually deployed to suggest someone is lying, for which you need specific evidence beyond believing a statement to be incorrect. That evidence is very rarely available in an HN comment.
It's hard to be thoughtful about using language, and I'm no exemplar. But a good start is just avoiding reflexively spitting out some rarely useful prefabricated phrases. This is one.
At other companies like Google and Microsoft I've had plenty of immigrant colleagues along with colleagues at offices overseas. Some eventually choose to return to their home country, some migrate here after starting at the employer.
The main game studio I worked for also had lots of chinese and korean immigrants on staff, but I suspect that was influenced by the parent company being korean.
(Spoilers: personal observation, it's pretty broken.)
In my anecdotal experience it's not so simple.
I would think a large contingent of GitHub employees want the people working at ICE to be using the best tools possible to achieve their mission. Many are probably quite proud of US government agencies using their tools, the same as if NASA or Executive Branch or Congress was using Github.
IMO it’s a very difficult situation when certain employees are arranging political protests against specific customers of the company, and making other employees uncomfortable to express their own potentially divergent viewpoints.
