If there is a lesson from the Boeing Max debacle, it is don't jump to conclusion of "incorrect maintenance procedures" like what Boeing did after the first crash with the Indonesian airline.

A lot of possibilities like Human/Pilot error, Equipment failure, Engineering design flaw, Freak bird collision accident, etc..

I agree with you. Since this is not a MAX just the most likely to cause this vertical drop. But yes, you are correct, lots of other causes need to be considered.

They didn't jump to that conclusion. They almost immediately knew it was MCAS but blamed the Indonesians anyway as a distraction.

Jumping to conclusions is one thing, deliberate disinformation is another.
