I assumed it was rho (ρ) of hydrogen since rho is used for density...

It's racist because it's racist. It has historically been used in a racist manner, and that's socially recognized. So, if you do it now, it's interpreted as racist.

(Much like the swastika is a hate symbol because the swastika is a hate symbol. It has been used as such and now it's socially recognized as such (even though there's nothing inherently bad about a bunch of geometric lines (and, in fact, was a positive symbol for the first 5,000 years of its use)).)

I added the repos to my existing arch install sometime last year I think. It's pretty seamless in that regard, I think I only ran into a mirror sync issue once, and it was resolved a few hours later.

My CPU supports the v4 packages, but I'm not really sure how much benefit there is for most things. (And things like tf/torch aren't coming from the repos anyways.)

I also use their kernel. I can feel a difference between stock and zen or stock and cachyos, but I don't think I'd be able to tell zen and cachyos apart tbh.

I definitely wouldn't switch distros for it, but since it's a trivial, drop in repo, I'll keep using it.

Adding another organization isn't ideal trust-wise of course.

Regarding the second point: applications change it. It's really annoying. I think Discord and Zoom both do it.

Remote SSH is the one that I need.

Anything Linux based is out, but I feel like there might be some surviving bsd that's a descendant of one of the paid versions. That being said, GNU utils are out and I don't know of any browsers that would work either (though there are utils to download and look at the source that would work).
