I think they are very different situations. Automattic (and their leadership) used their power over the WordPress open source project as a weapon in a legal dispute with a major competitor.

What has Anduril done? Tried to sponsor some conference. Post a job ad on a project forum dedicated to that purpose - both are activities which, in the general case, the project welcomes - and then project members object, not because of anything they’ve done in the project itself, but because they don’t like the industry Anduril is in, who its customers are, etc

Seems to me like completely different situations. The WordPress situation makes Automattic look bad in my eyes, while the Anduril situation makes NixOS look bad in my eyes
