@CONF iture:

AoA protect is there for a reason, don't have to explain you that, unfortunally it was activated when not appropriate, fortunately there was and is a solution to overcome.

Question: what will be the instinctive reaction of the PF when stickshakers are suddenly activated?

Both JTSB as ASC did not initiated an investigation, although you say the control was 'kidnapped',
nobody - on this forum -seems to be concerned about that one.........shouldn't we?

@Kimon:

I admit the dual ADIRUs/SAARUs concept in B will be more robust against multiple failures compared to the 3 ADIRUs concept of A.
In single failure and in case of similar but - wrong data - it will not make any difference.

FWIW:

In A350 airbus will supply the ISIS (optionally a repeater for RH seat) with its dedicated pitot and static ports.
The triple ADIRUs concept will remain however with dedicated multifunctional probes (MFP) and slideslip sensors.
Only ADIRU#1 will be equipped with an additional normal AoA sensor.
