If Richard Stallman, has changed the name of "Free Software Foundation" to "Software Freedom Foundation", He could have saved 2 years of his lifetime, not having to explain "free as in freedom, not free as in beer".
The issue isn't so much with the Foundation as with "Free Software" in general. It wouldn't make sense to call Firefox a "Software Freedom" project, but calling it "Free Software" does makes sense (just in too many ways at the same time).
