I most certainly think that if someone makes an especially complicated model, much more than what you see in the Klingon up there, that they should be able to sell it. that it should not be pirated. but it someone wants to present models for free, by doing so, you will have the full spectrum come at you and you should not be babyish and play games with your free gift.
to do so would be very rude.
again if it is offered as a prize for solving some puzzle or riddle of proceedures for release of the model, as a reward, fine.
again, you are JOINING a club and MUST OBEY THE RULES, if you want the reward. again, no pirating.
thank the artists and authors and hosts who presented all these free models, as I would have been stuck making my own crummy cereal box cardboard cutout attempts with no learning jumps from other's more advance creativity and skills.
when a society abuses and loses its artists, it usually fails.
