I disagree that the GPL subverts the 'normal' use of copyright (though I'm aware it is presented as such by the FSF). Tons of copyrighted works are licensed for distribution by 3rd parties. Software licenses which allowed unrestricted distribution existed before the GPL. What the GPL innovated on was to put light restrictions on distribution to ensure modified source code would be made available along with binary distributions. In a world without copyright, there would still be tons of software without publicly available source code (perhaps more than now, due to the inability to enforce GPL violations). Also, "information wants to be free" is more of a vague idea than anything else. I want information to be free. I'm a big user and proponent of open source software (heck, I wrote a non-trivial feature of Webtorrent). That doesn't necessarily mean I'm against copyright.
