RMS says Creative Commons Unacceptable

Mr A Coward writes "Richard Stallman has stated in an interview that he no longer supports Creative Commons licenses. In the interview carried on LinuxP2P.com, and which is largely about the P2P and DRM issues, Stallman ends by saying: 'I no longer endorse Creative Commons. I cannot endorse Creative Commons as a whole, because some of its licenses are unacceptable.' He suggests instead using the GPL for creative works." The crux of his argument is that, since he disagrees with some of the CC licenses, and people tend to lump them all together, he feels compelled to reject them all. What's your take? Are some Creative Commons licenses worth using, even if others aren't?
