Also, Bre Pettis has a lot of supporters who'll stand by him no matter how self-serving his actions. For example, people supported him using his blog to to publicly humiliate newbies to Open Hardware for not opening up their derivatives of his designs sufficiently. The same people later insisted there's nothing wrong with him closing off his derivatives of other's designs and that anyone who complains about this is hostile and inflammatory, even comparing them to terrorists - because of course, holding someone to the same standard they hold others to is far less inflammatory than calling someone a terrorist fundamentalist. I am sadly not kidding.

Edit: I wouldn't even be surprised if Stratasys managed to get away with patent lawsuits against open 3D printer manufacturers with him on board.
