The People's Federation of MediaGoblin.

Their national anthem:

GMG, savior of our fair content,
keep fighting on to free us from our chains.
We walked blindly to our own discontent,
until nary a true freedom remains.

Our four beloved freedoms you do give:
to use, to learn, to alter, and to share.
Through federation our content can live,
even as central services despair.

We gave up our freedom for convenience,
given to corporate oligarchy.
Due to that we must make our recompense,
and allow all media be made free.

Free as in freedom is our GMG,
saving our media for all to see.
