i can fully understand his concern about redistribution of his product in terms of piracy , but selling the product  and then telling you what you can and cannot do with the rendering you took of it  , is just ridiculous in my opinion , imagine Nikon or Canon selling a camera and then telling you , you cant sell the photographs you took with it .
his work is indeed top quality ,but having a rigid(insane) licencing  agreement is just going to alienate (if it hasn't already )the honest poser users . because iam guessing it sure has hell hasn't stopped his products from being pirated  thus far .
