The statement that Anduril sponsoring a NixOS conference was inherently damaging as opposed to the reaction causing the damage, "When did defense work stop being taboo" etc.
I've worked in the US Midwest->SFBay->US West and defense work never seemed particularly taboo in my circles, moreso that the work was boring and constricting.
Traditionally cautious sectors adopting a particular technology seems like a sign that a technology is viewed as having a particular level of dependability. That's a good thing.
