One issue about the "bitey dog" MCAS not mentioned was the story of Air France 447 (https://en.wikipedia.org/wiki/Air_France_Flight_447 https://en.wikipedia.org/wiki/Air_France_Flight_447). Thats the one that stalled into the Atlantic in 2009. The flight crew plus a pilot that was riding in the back seat spent minutes trying to debug the flight computer, and only realised too late that the copilot was pulling back on the stick the whole time, keeping the aircraft stalled. This happened because of mode confusion: the aircraft computer realised it had compromised sensors and had switched to "alternate law", in which the computer would not override a stall. I have no doubt that Boeing knew about this incident and did not want to create a repeat.
