Ever had a car with port fuel injection? Guess you should sell it, its all a knock off of Stuart Hilborn's designs. You should support the developer. -

Does you car have tires other than Goodyear? Yes? Better sell them. Goodyear developed vulcanized rubber. All others are imitators - period.

Is everyone pissed at Fuel Safe for copying ATL's fuel cell designs? No. Should we be pissed at Winters for producing knock offs of Franklin quick changes? How about Aluminum engine blocks? The first one was cast for McLaren by Reynolds Aluminum. Don't buy a car with an aluminum engine block, or you are a hypocrite.
Should I keep going? There's examples of this in almost every component of every vehicle.
This argument is stupid. If you have ever been involved in any form of the auto industry you know that it is all monkey see monkey do. Everyone copies eachother. Especially if someone is winning.
