The Indonesian NTSB blamed pilots, mechanics and Boeing equally. My opinion is that they were being overly-generous to Boeing.
I think the Indonesian accident root cause was an AoA sensor that was damaged and not noticed by the mechanics. Boeing’s vague documentation on MCAS was the next link in the accident chain.
Indonesia is literally at the end of the earth from the USA geographically, so also at the end of the earth for training and parts. Boeing needs to ship working planes to buyers who are already at an operational disadvantage compared to the West.
