Airbus has to take responsibility for indoctrinating pilots that the Airbus could not be stalled.
It doesn't. Notion that Airbus indoctrinates pilots that its aeroplanes can not be stalled is misinformed at the best and libelous at the worst.
I do not know why people still want to reopen this "stall" debate.
The most famous essay of Harry Frankfurt might improve understanding.
the 3 crew never realized they were in a stall.
Correct. They went into Birgenair mode; few unreliable indications caused them to overreact and stopped believing most of them.
we will never know what they really saw on the displays.
We can never know what the crew believed it was seeing (it is so for any crew on any flight that had the misfortune of being the very last recorded on FDR) but we can assume what was displayed with such a high probability that colloquial phrase "we know" can be used safely.
the audio and visual warnings were multiple and confusing.
Getting stall warning if one desperately tries to climb the aeroplane above its performance ceiling is consistent, not confusing.
How would some of you have reacted in similar circumstances ?
Who cares about PPRuNers! 30something other crews reacted not completely appropriately yet never got to the edge of envelope! Those who got stall warning either considered it spurious and maintained attitude or pushed and descended, therefore survived. There was TAM crew who pulled till stall warning, then pushed, repeated the cycle a couple times giving their passengers a hell of a rollercoaster ride. BTW, captain of West Carribean 708, MD-80 that was lost after high altitude stall manually trimmed stab to full nose up position in desperate attempt to keep the nose up. So much for the evils of autotrim.
There are lots of lessons to be learned from AF447, one of them is interface between automated systems and humans. That is worth spending a lot of energy.
