I think the problem here isn't that Harlan's mad, it's that he appears to be impeding other creators.
How is stopping someone from ripping you off considered "impeding?" if they are creators, then CREATE.
I don't see how this action impedes other creators.
That's a facile argument. Chilling effects are very real things, and we're probably lucky as a society that Ellison is viewed as more of a troublesome crank than any kind of real threat.
Earlier in this thread, we had someone crack a joke that if someone was hoping to be a science fiction screenwriter, the best thing they could do is
not read Harlan Ellison stories, to head off any possible accusations on his part. Another post pointed out how he seriously attempted legal action against the last Star Trek movie based on a completely unfounded rumor. Imagine if that had worked. Harlan Ellison, the knight in shining armor, defender of only the littlest of guys, manages to stop production a major motion picture not because they'd plagiarized him, not because they appeared to plagiarize him, but because they were rumored to have used something in a work-for-hire script he probably doesn't have independent ownership of. Granted, Ellison probably
wishes he had the kind of pull that his baseless claim of a meritless accusation could stop a film in its tracks, but something on that scale would only need to happen once for it to become a third rail. Consider, if you will...
A recent episode of Doctor Who had a time-traveling robot assassin indistinguishable from a human. Couldn't have that, Harlan might sue. Don't you know his livelihood depends on being the exclusive provider of time-traveling android assassin stories? What about a stone ring that transports people through time and space by walking through it? God forbid!
Were that it could be so simple that you could just say x is similar to y, therefore x was stolen from y. We'd all be paying royalties back a hundred generations, in that case. The Estate of William Shakespeare would be making a killing.
Actually, that last bit gave me a thought. Does anyone know if Harlan Ellison ever made any kind of comment on the
ungodly complicated WGA credit arbitration process? It seems somewhat at odds with his "I already published something that this reminds me of, so send me a big truck of money to make me shut up" approach.
