Coreboot (which System76 and Framework use): Exists
Love the GNU mentality though, but you don't need FUD to promote your ideas. Lots of problems would just disappear if most things went open-source, and the value proposition might shift but would still be there. The most valuable part of code is the people that create, understand and maintain it; not the code itself. The code itself is ephemeral. (I hate to admit this. Us coders love our brain-babies.)
Note: I own a System76 Thelio Major and have a Framework laptop on order, so I am not just a non-participating bystander in my beliefs here
That page was written way before most people had ever heard of linux, a decade before things like secureboot became a thing, and way before the most common personal computing device in the world was a choice of two locked down devices.
