The point is that the MAX design flaw is so shallow. It uses a single sensor. If the sensor malfunctions during flight, then the software instructs the aircraft to dive into the ground. No right-minded person would ever design a flight control system like that. It's not merely wrong but wrong in such a basic way, as if designed by a child. Such a situation reasonably makes people question whether the MAX project was managed by competent individuals, which is obviously a prerequisite for many people to fly in one.
