One of the strong hints that the GNU GPL is not meant to be part of a hybrid license with additional restrictions appears right at the top. Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Everyone who generates a "cut-and-paste" license out of the GNU GPL is plagerising, and violating copyright law. So actually editing the GPL to include more explicit terms is right out. If you wish to add additional restrictions before or after the GPL, then the total license become inconsistent. The GPL clearly marks the beginning and the end of "this License" with: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION END OF TERMS AND CONDITIONS The makes it fairly clear that "this License" applies to just the GPL. Not only that, but there's wording in the GPL that also enforces this point of view. Section 8 says "In such case, this License incorporates the limitation as if written in the body of this license." The reason why you can waive restrictions is that Section 2, Paragraph 2, allows you to. By generalising the entire Program under a more permissive license, a user may choose to use the more permissive license, or to use just the plain GPL. Simon
