Boeing is "right" in the sense that, if you follow the normal 737 flight manual, you'll be fine, even with MCAS enable or even MCAS misbehaving due to the sensor readings being bad or whatever. I think the problem is that the symptoms are different from other 737s, and if you don't KNOW about the MCAS stuff, that's very surprising. So as humans, even though logically the same procedure applies, instinctively you don't think to do it. And given the very short time frames involved, and the margin of error, it's not too surprising that these events have occurred. Perhaps the need-to-retrain criteria needs to include the following amendment: If the craft exhibits new symptoms, even if the response to those symptoms are covered correctly be the old operations manual, pilots will need to be retrained to account for the new symptoms.
