In my opinion, the Flipper thing is a result of business practices that create demand that outstrips availability.
A knife is 'dropped' in such a way as to make it very difficult for the average person to buy one. There's a big demand created by buzz ahead of time, there are a limited number available, loads of pictures showing off the latest acquisition. More and more people want one. Then BANG! They start showing up on auction sites and internet classifieds, and they are priced at ridiculous prices. That, in itself, excludes people.
The culprit, of course, is THE EVIL FLIPPER.
Nuts.
I understand that specifically in the case of the Forum knife that the people who did the work would want to limit opportunism, particularly since nobody seems to be profiting from this project. That's reasonable, in my view.
But, also in my view, if someone has bought something legitimately, it's his to do with as he wishes. He didn't create the climate that surrounds certain aspects of the hobby. Name calling doesn't change the laws of supply and demand.
