Shades of HAL !
It is shocking how this system was introduced- only being documented and publicised following the death of 189 people.
I can see the logic as to why they'd build it in- if it was 100% operational and reliable it would act as a safety measure. AF447 for example would have been saved by a nose down attitude to recover stall. The junior PF of AF447 continued nose up throughout a 40,000 ft flop. However, in that case it was faulty sensors too- frozen pitot tubes from memory, so the input data was bad anyway. Nose down however could have been useful for stall recovery in any case.
