Nothing is up with it that I know of, it's just that there are few stand alone USB throttles out there to purchase, so if somebody say finds a stick they like, of which they are many, if they want to get a throttle, they aren't limited to just the CH one anymore. I know a lot of guys start out with just a single joystick, and get used to it and either don't want to change to an entirely new HOTAS setup such as TM, Saitek, or CH, or can't afford a whole new setup. The TM throttle has the little rudder flappy things by the looks of it too, which the CH doesn't.
