The issue that resulted in the crashes was angle of attack sensors reporting broken data, which caused MCAS to nose down the plane; this is absolutely not what the pilots are talking about. Everything else that has been discussed (whether the pilots should have been told how to disable it and tried it in the simulator, whether Boeing should have added the second vane or even a third one on all planes, etc.) fundamentally depends on having incorrect data from the sensors and the plane not being able to deal with that. The exchange might hint that MCAS had an awful design history, but even a perfect MCAS could have had issues if supplied with incorrect sensor data; garbage in, garbage out. Now if there was somewhere an email about the lack of a voting system on vane readings, that would be another story.
