The critical part for derivative works is in regards to this statement: "The remedy for copyright infringement is either damages (money) or injunction (stop using the GPL code). "
Which begs the question - what is the status of the derivative work AFTER any damages have been paid? Does it remain subject to GPL terms or is it now free of them? Or is that subject to agreement (and quanta)?
I have to agree with airfishey.
