The freeness of the GPL itself is irrelevant. The FSF does not want people messing with the GPL and making it broken in some way and calling it the GPL. This will confuse licensees and make the FSF look bad. As the GPL itself is not software it does not need to fall under the DFSG. In other words, the DFSG only requires that the license allow derived works of the software it covers. It doesn't require that the license allow derived works of itself. Not that the FSF seems to care, as the Artistic license claims to be a kindler, gentler version of the GPL, and nobody has objected (presumably because the Artistic license doesn't claim to *be* the GPL).
