In my mind, Free Software is a strict subset of Open Source software, so we do try to limit ourselves to only Open Source software. I have no problem with Free Software and I would like to see more of it as well.
Well, pretty significantly, the two are separate communities, though the software classified under them might overlap. See http://www.gnu.org/philosophy/open-source-misses-the-point.html
And I have met many Open Source advocates who, when presented with a Free Software-only agenda, were angered to the point of flaming. I have also met the equivalent on the Free Software side (though it admittedly seems more dense there, perhaps in retaliation or frustration). Certainly there are very few considerations of the FSF at the conference, from what I've seen--official Twitter channel? iPhone apps? No GNU in the name? Flash videos for the streams (unverified)? Once again, start encouraging agnostic terms (Free/Libre/Open Source, for example), then maybe work into compromises that service everyone's needs. Maybe one day, this conference can truly represent digital freedom, but today, I'd settle for making everyone comfortable.
It's entirely possible that I'm making a general complaint that should rightly be personal, but regardless of its nature, it is a discrepancy between the mission and another part of the mission (see my previous message). That, at least, needs to be addressed. Does the conference truly wish to serve all people, or is it only people who feel comfortable with Open Source Software ideals? Does the conference really mean to focus only on Open Source, or do they really mean to incorporate other classifications as well?
Also, I want to re-iterate that I didn't "[stay] home because [I] did not think there was enough FS material[,]" though I think it might be a valid reason to someone. It would have been enough for me, and for everyone at the conference (I believe), to have represented all of the relevant communities at the conference: Open Source, Free Software, Creative Commons, Public Domain, Free Culture, Open Access....better to find a term that doesn't exclude any one (Free Culture, for example, is insanely inclusive, though maybe too broad for a software conference).
Does anyone have a good idea for an inclusive term? This is actually a major difficulty for the community, I think, in the face of the Open Source community, represented by a weaker term (see fsf article above), and the Free Software community, which is often perceived as too harsh or judgmental (e.g., RMS' comments on Steve Jobs), so if we can come up with a good term, it would have effects that extended past this conference (though the conference would undoubtedly reap the benefits of being a leader in this respect).
