alt Hacker NewsAgree in general, though with Libreboot the pedantry is more or less the point of the project. You fork a project and put 'libre' in the name, I personally see that as a statement of dedication and expect you to stick to those guns. The experiment isnt much of an experiment otherwise.
Coreboot still exists.
Libreboot is not a fork of Coreboot.
It's a distribution. That is, they build and distribute firmware images. Coreboot just ships source.
Coreboot's docs lists the variety of distributions: https://doc.coreboot.org/distributions.html
