bj read the section in the article you posted, "How the MCAS system works" and you will see were you went wrong with this comment.
"What to do? Boeing decided it would overcome the 737 Max instability problem with a piece of software which compensated for the 'nose down' tendency by forcing via software the plane's control surfaces to lift the nose. So a basic aerodynamic geometry flaw is fudged with software."
I think you meant nose up tendency as the aircraft approached the stall. The MCAS would induce nose down stab trim to prevent a stall.
