Either pilot suicide,
Or complete and utter failure of all airplane's critical systems

There is no other explanation for how the plane would descent so suddenly. Whatever the reason, the investigators will have a tough job and I am not even sure if the black box remained intact after such an impact
Chance of pilot suicide is very low. Airplane always have co-pilot. And i don't think another pilot want to die. Any sight of nose dive a hundred people airplane co-pilot will have trained to quickly prevent that?

The plane pitches up more than the pilot wanted

"Pitching up more than the pilot wanted" is not stated any where in the quote, it says "control force is nonlinear". This is not the same as "unstable". Stability has a very specific meaning in aircraft dynamics, which is explained by the first sentence in your quote. A unstable plane will depart without active input from pilot/computer, this is NOT the case for the Max with or without MCAS.

Fine, just semantics, the plane pitches up more than what the pilot expected at certain AoA when the plane is close to stall

It doesn't pitch up more, the controls feel lighter when the plane is close to stall, this is different to other 737, but not unsafe on its own.

But Boeing was greedy because they want to sell the plane to airlines as "just another 737", "don't need additional training", and didn't tell anyone about the whole shit show that is the MCAS.

On the rio->paris flight, along with bad instrument readings and sketchy stall warnings, the pilots got completely confused and crashed the aircraft. But that was at night and that flight went down at 10k a minute.

Exactly. Based on the graph posted by @daifo's post (Post: Breaking & World News! III NO DISCUSSION!! ), it appears to lose 20,000 meters in just 1 minute, then regain altitude and maintain altitude for 45 seconds, then lose crash. This shows perhaps there was a violent struggle between the pilots, with one pilot regaining consciousness to wrestle control back again, but get clunked over the head for final descent.

Air France 447? It was a frozen pitot tube, the Airbus fly by wire degraded all the way back to Direct Law but the inexperienced pilot didnt know and held the joystick back at full deflection pitching up 40 degrees causing the aircraft to stall until it impacted ocean at more than 200mph vertical speed instantly killing all on board. The airbus unlike Boeing uses sidestick instead of control column, so it wasnt obvious to the other pilots that the moron was pulling back on the stick as hard as he could (probably thinking the aircraft fbw system wouldnt cause a stall) the entire way down to their doom,when the captain finally woke up and figured out what was wrong it was too late to recover.... whatever happened in this case it wasnt storms or night time confusion and nonMax 737 do not even have FBW
