Usage of GitHub

[Svetlana Tkachenko]

Please do not use github. It runs non-free JavaScript, hosts non-free
software discover-able by its users, and encourages poor licensing
practices. https://www.gnu.org/software/repo-criteria-evaluation.html
has extra information. I believe a GNU project may not refer users to
non-free resources in this manner.

I believe as an alternative, a Gogs instance provides functionality
similar to GitHub and may be self-hosted.
