To be fair, the situations were different.
In the Airbus A330 iced pilot tube situation, you did not need to change the aircraft state to recover. You just needed to hold the current pitch and power setting and eventually the airspeed would return. In the 737 MAX MCAS scenerio, you need to make a
prompt and active response, and the situation would never resolve over time. Moreover, the 737 MAX MCAS scenarios all happened at low altitude, whereas the A330 incidents were in cruise.
