According to most people that use the term, like the FSF and Debian, a CC-by document, a BSD-licensed document, and a PD document are all free. In the absence of a copyleft, however, derivative works may become non-free. (The original work, however, will ''always'' be free.) And thus, arguably, the restrictions are justified for the cause of freedom. Nevertheless, they remain restrictions on freedom. Also, you don't need a copyleft to keep "it" -- the original document -- from being controlled. A PD document is always PD, a CC-by document is (assuming that the original licensor indeed had the right to license it) always CC-by, and so on. Only derivative works may be controlled. Thus for example, the PD Grimm fairy tale Schneewittchen remains free, even though the Disney movie Snow White (a derived work) is not free. I believe that mav, Andre, and I all have slightly different opinions about what is important in regards to freedom and how to safeguard it. But it's very difficult to discuss these things with imprecise language. That's why Richard Stallman makes such a big deal out of terminology, even to the point that he annoys people. I use RMS's terminology, even though I disagree with him on some points as well. -- Toby
