I wasn't suggesting an open market place as the only option forcing people to buy tidbits. I only suggested that if people can participate to get something for their creation then that would be driving force in itself to spread construct. If instead you pay once for a product to get all free stuff then I would think you would miss the driving force you otherwise have with the other option.
With a free version you compete with other free product. With a paid version you compete with other commercial products and that makes it so much more difficult. With a free version you also have the spreading effect because it looks more sincere.
Well any way as long as the free and open source version is thriving and growing people will grow with it and I will continue create video tutorials.
