The attitude of content creators today scares me a bit. I was in a conversation with two artists the other day, one professional and one amateur. They both firmly agreed, that drawing someone else's characters as a commission was morally wrong and legally grey, and when I asked why, they say, "Because they're taking my money."
"But you wouldn't have gotten money there anyway, if they had never produced the art." I argued. They countered by saying, it was stealing. "But what would it cost you?" Nothing, they said, but it wrested control from them, and potentially could lose them the rights to the work. "Wait- howso? You retain ownership, you're simply letting others use your work as inspiration and get paid for their efforts. It in turn, draws more to your story, your world- who loses?" They argued that was the 'exposure' angle, and I didn't really know what to say- I mean, I wouldn't have watched Sherlock if not for the legions of fanart of it on Tumblr, or listened to Jay-Z if not for the works of Girl Talk.
They argued, all content should be original- but I can't fathom that. Is art, similarly to science, not an iterative process based on the input of dozens, hundreds, thousands of people that came before us? Are we all not standing on the shoulders of giants, pushing just a few steps forward more, both because we like what came before us but want to see it go someplace new?
I wish we'd all stop feeling so threatened, I suppose.
EDIT: I should emphasize, I admitted they had the right to request no one use their characters, and if anyone did they clearly were an asshole. But that doesn't mean I wouldn't think doing so was a mistake.
