Just to see if I am getting delusional Thorsten's argument correctly: he is saying that one should take this material as if GPL licensed or any other of free-License, as a matter of fact?
Or is he saying, because there is material that is not GPL, then GPL can be treated as such?
Mind-boggling

I may be naive, but that read NON-GPL to me. Not even covered by any sort of free license.
