Has that been confirmed or are you just assuming it was the cause of the second crash?

The public flight data looks very similar; for lack of any further details people will assume the problem had a similar root cause. Either way, his point isn't wrong- enabling a feature that can take control of the aircraft where it could not previously needs to be properly communicated. If pilots flew the older generations for several years they would not expect this behavior.

Not yet confirmed, but all evidence points to it.
Even without a single confirmed crash it's a strong SW security problem.

I disagree your conclusions, as the cause of the two crashes was not determined yet to my knowledge.
But your description of the problem sounds plausible at least, so I upvoted your comment anyway.
Previously anti-stall just signaled a warning, now it automatically turns the nose down, fighting the pilots attempt to ascend the machine after a start.
This is a serious security defect.
#1 anti-stall being fooled by some strong AOA sensor signal on initial ascend. This is not a stall, this a normal start procedure.
#2 anti-stall turned on by default automatically.
This already caused two major crashes with zero survivors. The attempt to blame the pilots not reading the updated documentation is also criminal behavior. Boeing might go bankrupt over this. I hope so.
