Not everyone has a setup with an actual clutch pedal mate, for them this is the only effective way to launch the car. You may not agree with it but it is not cheating. Cheating would be doing something like braking overly late and banging down through gears unrealistically quickly to get the car pulled up. Or taking advantage of exceeding track limits where a penalty isn't applied for whatever reason.
