That's not my reading of it.

However my biggest issue is the conflict of interest between Eelco -> DetSys -> Anduril Contract -> Eelco fighting hard for Nix to sponsor Anduril.

As foundation chair he should declare that he doesn't have a conflict of interest and DetSys doesn't have a contract with Anduril or have recused himself from the sponsorship discussion.
