The Scrivener's Error picks up my post on Creative Commons misuse and describes the problem in code:

Alex Wild doesn't quite go far enough in criticizing the (mis)use of the Creative Commons license. The real problem is that it is not a license, and is therefore misnamed; it is, instead, a revocable covenant not to sue:

If you limit your use of {this CCL work} to {insert particular subspecies}

then the current holder of the rights to {this CCL work} promises not to enforce his/her/its exclusive rights to {insert particular subspecies}

else the current holder of the rights to {this CCL work} makes no promises whatsoever and you are subject to his/her/its whims under the full range of copyright, trademark, and other relevant law

end;
