>the MAX was a flawed design due to the expectations it placed on pilot training, competency and in particular, instinct in a surprising situation. That's it.

As you eluded to earlier, there are usually multiple causes. One that the above statement seems to overlook is the poor application and adherence to the system safety analysis. According to their own process, even though they misclassified the failure they should not have relied on a single sensor.[1] It seems to me there's engineering, process, and human factor causes involved.
