The amount of time it takes to share something isn't the problem, although I have run into some roadblocks with that too, mostly with Google +. What I'm saying is I shouldn't have to share a model in order to use it, free or otherwise. The price of free should be free. No strings attached. Such as it is with Turbosquid and other similar sites. I don't think sharing is bad, I just hate that it is a requirement.
