It requires a fairly expansionist view of copyright to make it inconsistent. The FSF has made similar claims in the past (for instance, that all Emacs Lisp code must be GPLed), but I'm not convinced that arguing for more Draconian copyright laws helps the free software cause. Copyleft requires compromises in this area, of course, but some deals should be off limits.
