This addresses a problem identified in both accident investigations: that pilots took much longer to recognize and react to an MCAS fault than Boeing had assumed. By stopping any erroneous uncommanded movements automatically, the redesign takes the response out of the pilots’ hands altogether.
Over these months I've become more and more bewildered by certain design-logic. Now this. What is it supposed to mean? Movements that are un-commanded, presumably meaning by the pilots, must mean movements made by MCAS. These are now going to be stopped automatically.

MCAS did not fail. The specifications/algorithms, altered late in the day, were to blame, inasmuch as they caused a catastrophic overload of warnings and handling difficulties that were beyond 'the average pilots' ability to manage. If MCAS is the only answer affordable answer, the suggested fixes, aired over the last weeks, sound logical.

Where are the erroneous un-commanded movements going to come from, given the quote implies it's not from the pilots and MCAS has been made safe?
