I don't quite see the argument myself. As a former dancer in the breakdancing scene the premise of "biting" (stealing) moves comes up a lot. After a lot of consideration I came to the conclusion that if you perform something publicly its pretty much fair game for copying. I don't think there is a benefit in spending your time trying to hunt down these copycats. The time is much better spent creating new works. The Open Source world teaches us that product is not just the object the item being copied but the service, the knowledge, the understanding of the product and the ability to create more. For creatives and dancers it's the brand, and/or your name. By all means if you think its worthwhile you can hunt down people ripping off your stuff but if you're becoming tempted to just sit on your prior work and prevent anyone else from touching it you're becoming stale. Case in point would be Cliff Richard who the RIAA like to roll out whenever they want to extend the terms of their copyright because apparently Cliff Richard relies on this royalties as his pension. I often wonder why he didn't/doesn't have to save for his retirement like everyone else.
