OK... look at the Open Learning Interplay conference page. I'm saying this is a group of people who don't care about free software, as in "free as in freedom" software. This is not, actually, a controversial statement. The honest response is "Correct, we are not free software advocates, we're 'open educational resource developers,' which is different; that's why we made up a different name." Or "Correct, we're learning science researchers, and software licensing is not our concern."
Neither one of these groups makes any pretense of valuing freedom, so it is quite obvious that when they get together, they won't be talking about software freedom. But they will be patting each other on the back about their "openness."
I don't have a beef with OER people, the only problem is that the students of the world need somebody to try to get the learning sciences to take software freedom seriously. Each missed opportunity hurts.
