Imagine if a single vane activated a stick pusher at low altitude. Would you blame the stick push system or the design of a single vane having so much authority?
The reliability of AoA sensors is fairly well known in transport aviation, certainly by the world leaders in transport airplane manufacturing. I would blame the OEM manufacturer, who chose to rely on a single AoA at a time, and failed to determine and understand what the consequences of failure could be.
