You really should not be in open source if you believe it is your purview to ideologically police the usage and contribution to your software. That notion is incompatible with the spirit of the endeavor.
"If you don't want to help create war machines you can't contribute" is your solution, not mine.
Historically the conventions of open source has been that use is completely without restriction, but there has always been conflict about that. The domain is new enough that I wouldn't consider it settled yet.
Also AFAIK one of the conferences objected to their presence, so they weren't able to have a booth there. Individual participants are in their right to make these decisions and act on them (like that one conference did). What exactly is the outcome people want?
Most wouldn't have a problem with Anduril donating and asking for no sponsorship or other benefits in return.
