Actually, I intrepreted his statement completely differently.  It is not uncommon for an artist filing an infringement claim to make a statement to the customers of the product in question.  SteffyZ did the same thing when ByteMeOK's textures were in question.  His original post did not appear to be meant for inciting anything, just a notification that people may have gotten ripped off.  It was a very brave thing to do.  As for entering into your thread, why should he forfeit the opportunity to defend himself just because you started a new thread?  In addition, there were several posts calling him names such as drama queen, where is the evidence that he actually he hijacked the thread whereas just opened himself up to more criticism?  I think a lot of people have tried to incite more drama by taking some of his comments too literally.
