Because it’s not a helicopter! It’s a fixed wing aircraft, making it very much not a helicopter.
It would also be reasonable to rename an aircraft class if it was significantly different from other aircraft. For example, an electric, vertical takeoff fixed wing aircraft that doesn’t require a pilot could be reasonably different from airplanes and helicopters to warrant a new name.
