On top of that there was a single angle of attack (AoA) sensor active that was complained about and failed hundreds of times. [1]
Not only is that a single point of failure, it is more easily sabotaged or easily damaged.
Besides the fact the plane has engines too big for it and needed this MCAS system simply to retrofit and route around regulations and deal with that by constantly checking the AoA to trigger nose down adjustments, this is bad engineering/product design by management.
The software now takes two sensors into account in case of a failure of one but is still a problem potentially. Not sure if software can solve this.
