RMS is extremely radical but he's also reasonable and consistent unlike these guys. There's also GNU Guix which recently banned AI-assisted contributions [1] due to copyright infringement concerns and licensing doubts. This is an entirely reasonable take for a hardcore free software codebase, it's literally built around this political concept.
On the contrast, libreboot's stuff reads like a parody or a shitpost. It's hard to believe they're being entirely serious.
