Someone has gone to the trouble of working out those settings, providing them for free and then putting a restriction on them. So what? How is that greedy? I always wonder at people who complain about others who give items away. The chances of two people finding exactly the same surface settings, via dial turning or numeric input, are probably fairly slim. That person obviously doesn't want commercial derivatives of their work, that they provided for free, being sold. I don't see a problem with that.
Yes, some people in Poser land are way too greedy.
