From the article's title, one might get the impression that pilots have been saying that MCAS is dangerous. What I was trying to do was distinguish between possible MCAS incidents and safety concerns, complaints about Boeing's nondisclosure of MCAS, and pitch-down incidents that had other causes (incidents of the last case seem to be related to the autopilot, rather than MCAS.) The latest crash certainly looks suspicious, but we don't really know yet, and the Lion Air crash occurred before the details about how MCAS could behave on sensor failure had been revealed. One would certainly hope that after this was revealed, all Max-8 pilots would be well prepared to recognize the situation and handle it, which might suggest that there is something more (or different) about this case (which could be worse news for Boeing).

  There certainly seems to be a regrettable attempt to diminish the differences between this model and its predecessors in that case. With regard to the MCAS specifically, once the cause of the Lion Air crash was determined, the FAA issued a new Airworthiness Directive [1], and I would be surprised if this information was not sent to all operators globally. For obvious reasons, pilots tend to take a keen interest in matters of aviation safety, so I wonder if this was not simply a repeat of the Lion Air crash (which, as I said elsewhere, might be even worse news for Boeing.)
