It's a non-sequitur, why have a problem with Anduril being advertised but not have a problem with Anduril using the software (i.e. because it's FOSS)? Anduril also gets much more value out of, and furthers their mission much more by, using the software than they do from advertising. And if you have a problem with software being used for military purposes, why are you contributing to a project with an LGPL license instead of one which forbids military purposes?
