The FSF seems to be primarily focused on providing information and tools to those who wish to seek it. At this, I believe they do a pretty good job. There are other organizations focused on selling the idea of F/OSS to outsiders, such as OSI.
First bullet point.
Realistically, these sorts of organizations are not looking for outside support. They thrive on controversy and know their target audience well.
I don't financially support the FSF, I don't financially or intellectually support Greenpeace, and I think the politics of groups like The Yes Men are tedious. I also don't think any of them are going to change the world.
I do respect the hell out of all of them though.
