1. Fixed the first one.
2. Whiteness is a construct and is deployed across phenotypes, geographical markers and the like: https://en.wikipedia.org/wiki/Whiteness_theory. This is how folks like the Karshadians are able to also deploy a sense of whiteness on a global scale: https://ajammc.com/2017/08/29/armenian-whiteness-america/. In short, in the way that I can't run from my Blackness because of whiteness, society will not allow you to run from that. It's on how you utilize it that makes a difference.
3. I'm going off the word of the founder of Elementary, who's highlighted that (and you've blocked?). To follow your example regarding System76's COSMIC, what's available to people (i.e. a layperson isn't building Comet from source, they're pulling it from AppCenter) is what they'll perceive as available. If you haven't updated it, that's on you to fix (and that's easy it sounds like).
This is something Angela Davis wrote about as well.
