UPDATE:
The community here and in various other places where Libreboot users are
prevalent, has decidedly voted in favour of a reunion with the GNU project.
See update on the Reddit thread:
https://www.reddit.com/r/libreboot/comments/66tdds/proposal_for_libreboot_rejoin_gnu_community/
Alyssa Rosenzweig, Libreboot's designated spokesperson, is handling the
re-join in addition to all communication with the GNU project.
I have stepped down as leader of the Libreboot project, while still
contributing to it.
