I think that's a very binary view of GitHub - it might be non-free, but given the huge community it has amassed, it's almost suicidal for projects to leave it, as they'd be reducing their contributor-base significantly. Projects that are hosted outside of GitHub get way less contributions and I don't think the Emacs users would benefit from this. I know that the people in FSF care a lot about freedom, but I care more about building the best Emacs packages possible, even I have to make some ideological compromises from time to time.
Love it or hate it, GitHub helped a lot for the revival of the Emacs package ecosystem. Especially when you compare this to the days of EmacsWiki and SourceForge. I wouldn't take any steps to discourage package maintainers from using it.

Kicking them out would be unkind. But asking that new projects going
forward use a different backend seems reasonable. That ideally should be
accompanied with a few recommendations.
Emms has been always been hosted on Savannah (for many years now), and
it works well for us. Emms is a mid-sized Emacs package with relatively
light development work. Savannah has been a stable and reliable home
over many years.
Personally, I don't prefer to interface life or work through a browser,
so the features, or lack thereof, of the Savannah Website never bothered
me. For Emms we use the mailing lists Savannah provides, Savannah's git
repo, and I try to keep an eye on irc for people commenting about
problems and improvements.
As an Emacs package, yes, we have been asked by many people over the
years why we don't just use github, and I'm sure that Emms is indeed
mirrored there and therefore has been, without any of the copyright
holder's consent, been added to microsoft's mass code theft project.
