> system affects how the flight stick feels and that's really it

I kept hearing this too, so I wondered why they didn't just directly change how the stick feels, like with a force feedback system?

And I looked it up[1]: Turns out MCAS was also there to push the nose down at high AoA, to imitate what the 737 NG does even in the absence of control input, so it's not just a stick feel thing.

"The added nose down trim has the side effect of requiring more elevator input at high angles of attack", so simultaneously fixing the stick feel issue.

It seems to me like MCAS solved two related problems at the same time... and sadly thus created an even larger unintended problem.
