I have also to agree with you (PyroSamurai), when you say that "free culture"
is different from "free software culture" (or "libre culture", as you seem to
have suggested, if I'm not mistaken). I don't feel comfortable when seeing
people calling us "free culture activists" or such things.
I have answered some people with an explanation about my views on the "free
culture" movement, and the answers are here in this very same topic (there
are at least three of them, so I suggest you to use your browser's search
function in this very same forum topic). Besides, I plan to write blog posts
about the differences too, both in English and in Brazilian Portuguese. And
I'll of course link to the blog post here in this topic when it becomes
ready.
To summarize it, just like RMS said some time ago, I'm also only concerned
with half of freedom 2 (half of it would be: "to redistribute copies of the
original versions non-commercially", which is like saying "to share the
original work"). However, just as the GNU Free System Distribution Guidelines
points out, in the case for free system distributions, the freedom 2 as a
whole must be given for the non-functional data. Remember however, that this
is just a simplification of the arguments I've presented here, and as such,
the references must be pursued in this very same forum topic and we must also
take into account the licenses of the works, not just mere written words.
