I don't understand all the hate for Harmony Gold regarding Jetfire. They paid for the exclusive rights to something, and fought to maintain it.
Hasbro would do the same thing if Mattel released action figures that looked like Optimus Prime.
It's just a part of the system/game.
Well, that particular Jetfire was just a G.I. Joe aircraft in Jetfire's color scheme, which didn't come from Macross.
