A well known and respected member on Pirate had similar dealings with Dewalt only it wasn't a secondary market they were trying to quash, it was any black and yellow cordless tool on eBay they went after. He got his ad yanked, a cease and desist letter from Dewalt, all manner of bullshit over just trying to dump a tool on there he had no use for. The ad wasn't deceptive or misleading, they were just going after anyone selling anything that even remotely resembled anything Dewalt. It was a fairly drawn out saga with him reporting on it at every turn and they were just a bunch of bastards about the whole mess.
Also the precise reason I will never own a Dewalt tool. If they buy Milwaukee, I'm going to be a very sad person.
