Some question: Daz can put any thing that he wants with his copyright, but they are legal. He can put in his copyright that you can't use xxx method for creating derivate meshes, but if they haven't legal rights for forbiding you to use the xxx method, you can simple ignore what they say. The best thing is to find what is legal and was isn't in Daz copyright statements. Consult a lawyer and not what Daz is telling. Second point: If the Daz impositions are legal and this causes harm to the Poser community, just publish this restrictions in all Poser sites, and then nobody more will buy Daz's products.

Stupidity also evolves!
