In both cases, the developers have respected your freedom; they have not tried to trample your freedom. The difference is, with copyleft we go further and we actively defend your freedom against anyone who would try to be a middleman and take it away from you, whereas the developers of non-copylefted free software don't do that. They have not tried to take away your freedom, but they don't actively protect your freedom from anyone else. So I think that they could do more for the sake of freedom. But they haven't done anything bad; insofar as they have done things, those things are good. So I won't say that they are wrong, I will just say that they could do more. I think that they're making a mistake.
