Signatories to the letter against Anduril sponsorship of NixCon include contributors with thousands of Nixpkgs PRs each, like Infinisil, wegank, and Ma27, plus many other recognizable names with PR counts in the hundreds. Some of those people are also committers who have helped many, many contributors get their code in.

If you can't tell that from a glance at the signatories list, you shouldn't be commenting on 'non-contributing participants'.
