Over the last few months, the Libreboot project has been having some issues with the GNU project. Quoting the Libreboot home page:
FSF, GNU and RMS: Libreboot is no longer a GNU project. Please honour this immediately, and formally declare that libreboot is no longer a GNU project. Leah is *NOT* stepping down as Libreboot’s maintainer, she is simply taking Libreboot away from GNU. Libreboot will still be developed as always, under the same standards of freedom as before, just *without GNU*. She has not forked libreboot.
Cat herding is difficult. I could see how the FSF would have issues with not having Libreboot, GRUB and GNU/Linux as part of their “full stack”.
