Nope, this is 100% false. The purpose of MCAS is to give the MAX the same aircraft handling characteristics so that it retains the original 737's type rating. Thus 737 type rated pilots can fly the MAX under their 737 type rating. A big part of selling the MAX is type rating commonality with the airlines existing 737-train pilots. Juan Browne, a real 777 airline pilot, mentions this in one of his excellent YouTube videos (https://www.youtube.com/user/blancolirio).
> I have been a pilot for 30 years
I suspect this person is a private pilot with no actual airline aviation experience.
Edit: This is the same guy that boosted his aviation credentials by citing that he's flown a 757 simulator (https://www.eetimes.com/software-wont-fix-boeings-faulty-air...). So yes, he's a GA pilot that has flow in some aircraft simulators.
> Among Boeing’s critics is Gregory Travis, a veteran software engineer and experienced, instrument-rated pilot who has flown aircraft simulators as large as the Boeing 757.
