Permissively licensed software is still free software. The BSD licenses are approved by the FSF as free software licenses. They're simply not copyleft.
Yes but what I think previous poster meant is that you can't use a permissive license and then blame RMS when you feel used by a corporation using it to make proprietary software.
edit: because RMS/FSF's position is not simply "all free software equally good and you should spend your time building some with any license"
(FWIW, I was also trying to add a charitable shift of blame to the article title making the matter more confusing by invoking the term Free Software; but, icouturi's correction of that little quip I added--which was entirely ancillary to my overall argument, as you point out--is, in fact, correct.
