I really don't get the NixOS/Anduril thing. Lots of complaints about arms dealers, and I'm not a fan of Thiel, don't get me wrong.
My understanding is that NixOS is free software, so Anduril aren't prohibited from using it, right?
If they are using it, why wouldn't you accept their contributions back upstream if they are useful?
Wouldn't we me more mad if they were using it and keeping all the changes to themselves?
