There is so much incorrect information in this thread that I would not even try to start to fix it, since it would just cause more confusion than is already there. I would just remind people that
a) discussions of licensing issues are off topic on this mailing list b) you should ignore all such discussions, since they invariablly include lots of legal-sounding opinions from people who are not lawyers and don't know, and often have significant misconceptions. c) remember that even lawyers don't know what the exactly implications of copyright law are, juries often surprise. So even if you go ask a lawyer, you won't get a definitive opinion.
