No argument from me there.

I'm not too sure about that. If a company uses GPL code, without  
releasing changes they've made, they are in violation of the GPL, and  
the original author can force them to release the changes. Without  
copyright, you don't have such recourse.

Free Software" was just published on GrokLaw:
