> The few core developers they have do not work with modern tools like git and collaboration tools like Github, and don’t accept contributions, although they may or may not accept your suggestion for a new feature request.

Git is not modern. It is many executeables, and Git repos are a many files.

GitHub is not modern. It is closed source huge RoR application.

Fossil SCM is features of Git and GitHub much improved, and in small portable fast executeable, storing repos in much smaller space in one SQLite file.

Apache is not https://copyfree.org license. I prefer copyfree licenses.
