I think I agree that they shouldn't use "open source," but again, this confusion highlights that you have to put in work when it comes to this topic. Free Software has the GPL, and all its related, healthy controversy. It's not perfectly clear, but it's far more battle-tested than the much more nebulous "Open source." People who like "free software" put in work, and better understood that, to some extent, you can't have your cake and eat it too. "Open Source" is much more about a whole lot (to me, naive) wishful thinking. (The OSI is a bunch of companies in a trenchcoat, the creators of the GPL were more principled.)
