I read yourdispute. I can sympatize for the lack of answers you got.
But you might be in error. Like seriously. Consult an honest lawyer beforeyou do real legal action. Because you might be dead wrong about your copyright issues.Not the least because evenif you are "right", it might still fall under fair use doctrine and all your claims would be void, no matter the licensing issues. And that you tried to revoke an unrevokeable licences after the fact tells me, you do not really know about the legal stuff.
The resaon i advise youto consult an expert is, because you are liable for damages, including lawyers fee of the accused, if you neglect considering fair use or worse, file it under bad faith.
