The problem I see with both sides of this argument is simple: both sides are wrong. It's pretty arrogant and hypocritical for iminnme and other customizers to get all cheesed off about someone stealing their work, when they themselves are breaking the law by making over-priced unlicensed figures in the first place. And the recasters are wrong for not at least compensating the original artist. So, both parties only have each other to blame for whatever the outcome may be.
This times a thousand. I have zero sympathy for these artists if they whine and complain about others "stealing" their work. When the artists start mailing proceeds of their profit to the studio, producers, actors etc etc, then we can talk.
Until then, pot meet kettle.
