Nah this is lame. If its in the market place then it should be usable to make commercial art period. That's what the market place is for. Now I have to go and read every license and make sure, even though I plunked down $$$ to buy it, I can only use it in a pic I do privately for no profit. That's like buying a t-shirt but you can only wear it in your bedroom. The marketplace is fair game. I'm paying for the item for crying out loud. How much more recognition and reward does the author want?
