all kidding aside, I know of only one time when someone got a cease and desist order from a legal rep of MOPAR. The man I know made a nice documentary about MOPAR cars and made DVD's and sold them via magazine articles ( car racing magazines, etc. ). Even though the documentary really promoted the brand a LOT and was obviously cool product, they sent him that letter.
He had to stop putting ads in the magazines to promote the sale of those DVD's.
but I think he somehow managed to sell most of the DVD's he had ordered up front from DVD maker...and go this money back from that at least.
