The crew did everything just wrong. It killed them.
They did what they should have done, by removing power to the stab trim motors, but then re-engaged them, and accelerated beyond the limits of the aircraft.
"Porpoising" wasn't a necessary action: stopping the stab trim was, and that procedure hasn't changed in donkey's years.
The crew simply failed to fly the airplane, and this demonstrates that the chances of a successful outcome are far less when passengers occupy the cockpit, rather than pilots.
If the airplane was an NG with no MCAS then they would not have died.
