My personal opinion: Most of the modellers had many hours to create some pieces, in most of the cases they feel good their pieces where used in images. They give their creations for free while having fun to model it, they don't want to make money and also don't want that others make money without of recognice of that. It's not the point that the modeller want some of the money, he wants to know that someone makes money with his pieces (Feedback). If you save time because you can donload things for free, why not use a little bit of this saved time for asking about permission. I personally had never received a "no" when asking for redistribution, conversion of pieces with some of my characters. All the times the original creator had given me the OK and a thanks while asking first. And thats the same i do, i had and would never say "no" because i feel good if someone use my creations. SHARKEY
