By the time it got to stop, aeroplane was truly stalled and flight controls were trying to satisfy 2.5G demand which, as we all should know, is impossible to achieve below 1.58 Vs. Demand was given using RH sidestick. Do you dispute that or rather you believe that actual problem is dumb computer obeying supposedly intelligent human which got confused? Do you really want more intelligent computers recognizing when thinking in cockpit has stopped and taking over? IIRC one of the main complaints on PPRuNe was: Airbus computer doesn't let me to do what I want, sob, sob.
Well, on AF447 computers got confused by losing all three speed references so "decided" not to interfere with pilot's demands. That's what is meant by very technical expression "ALT2".
