First, I think b is not an exception but a restriction. Adding any restrictions to plain GPL results in an invalid licence as in http://lists.debian.org/debian-legal/2006/05/msg00303.html That isn't much different to using the plain GPL with an OpenSSL-like licence - both licences are DFSG-free, but we can't satisy both of them simultaneously without additional permission on the GPL side. Of course a copyright holder of the entire work could still copy and distribute and so on because they don't need a licence but we can't because we can't satisfy both of those restrictions simultaneously. The copyright holder could make a new licence out of the GPL, as permitted by the FSF, but they have not done so. I think they should use the plain GPL, because I dislike licence proliferation. I'm surprised that Red Hat have produced an inconsistent licence and I'm surprised that GPL+restrictions isn't widely-known as non-free.
