There will always be people who will share their work for free. That is their privilege. It is also their privilege if they decide they may wish to earn a few dollars for their efforts. Nobody is forced to buy. The microcomputer has been around long enough that we are swamped with companies selling commercial computer products. Yet the web is still full of free software and some of it is quite superb. On the positive side there have been many Poser freebies that while quite good fall short of perfection. If creators are given a financial incentive they may just go that extra bit that makes the difference. Personally, I see nothing wrong with commercial efforts and hope to see some interesting results from it. In fact, Renderosity may look free but somewhere along the line it is costing somebody something. I don't mind taking up the slack with the occasional purchase.
