The conclusion is most charitably described as fanciful. There are strict rules about an automated system being able to apply more "authority" than the pilot can counter, which every engineer and manager involved knew well.

There are strict rules about a single sensor failure that can make the plane unflyable, which all knew well.

This is not a case of simple negligence to check documentation. This is a case of deliberate coverup of known risk factors to dodge rules specifically intended for airframe changes of this kind.

It was the process of dodging these rules which kept the MCAS design from being reviewed competently.
