Agreed, but I think it's worth lamenting the danger in that. History is certainly full of transitory calamity and harm when semantic shifts detach labels from reality.

I guess we're in any case in "damage is done" territory. The question is more about where to go next. It does appear that the term "open source" isn't working for what these folks are doing (you could even argue whether the "available" term they chose was a strong one to lean on in the first place), so we'll see what direction the next shift takes.
