I'd personally forget about it and focus on working on making the game the best it can be. Some people will never pay for the game no matter what and the ones who are ready to pay (and therefore matter) need as motivator a solid game (it's looking very promising, imho) and a good price (I consider my preorder cheap). The only reason to bother with this, aside from agreeing that people should respect other people's work, would be the people that takes an alpha (or beta) as if it was the final product. Surprisingly, those people do exist.
