How could an article from March 2019 take into account what Brady is saying
now ?
MCAS is a longitudinal stability enhancement. It is not for stall prevention (although indirectly it helps) or to make the MAX handle like the NG (although it does); it was introduced to counteract the non-linear lift generated by the LEAP-1B engine nacelles at high AoA and give a steady increase in stick force as the stall is approached as required by regulation.
I'll add that that trying to give an increase in stick force with a control slower than the stick-controlled elevator raises questions...
