FSFE - Free Software Foundation Europe (fsfe.org)

The current state of the network is definitely not as good as it should be, but I think the idea is still good and it goes into the right direction. Especially as FSF* are traditionally quite user/people focused and less corporate focused. Therefore I think it fits your idea of grass root communities quite well.
