Teller, of Penn and Teller fame, is suing a guy who has created a set of instructions for reproducing one of his tricks.
It's not even a new trick.
But the guy is apparently selling a DVD with the instructions for about $3000.
Boom, sympathy out the window. Just another example of how the profit motive removes any moral protection for copyright infringement. Frankly, based on my judgment of the personal characters of misters Teller and Penn, based entirely on the style of shows they choose to put on, I daresay dude would have been okay if he just hadn't tried to sell it.
A-OK in my book to go after him. And in this case the expansion of fair use to cover non-commercial use could mirror the reality of the situation, creating a nice overlay of the law over society's own view of morality.
