Nix / NixOS

I read the thread and now I'm more confused. Can someone explain what this is about to an outsider?

Edit: every thread I see is talking about talking about a discussion. What's the discussion??

Edit 2: Ok so far I got that this Jon guy doesn't like positive discrimination and 'politics' and also worked at the defense company that sponsored nix but doesn't support that (?) (which is also related to the diversity problem (?)) and there are also two open letters that are related (?) and people have been mean to him in threads. Anyone who isn't involved in nix community thinks good of him because he's very active and talks agreeably

I wish they'd all stop talking so superficially and just get to the point
