It's very regrettable that Boeing isn't holding its senior executives to account for the flawed strategic decisions that have severely damaged its brand and its reputation. Decisions that of course have also tragically cost many innocent lives. One can only hope that the 40% slide in the share price and the recent high-profile order cancellations will be a wake-up call.

I'm guessing those questions are rhetorical, but for the avoidance of doubt: Yes and yes. The info is in the text of the updated AD I provided a link to earlier. I know it's not an easy read, but pulling out the relevant parts:
A. The unsafe condition is described thus:
The FAA is issuing this AD to address deficiencies in the FCM software that could prevent continued safe flight and landing; to prevent unrealistic, sudden drops in displayed airspeed at high actual airspeed, which could lead to pilot control inputs that could exceed the structural capability of the airplane; to prevent simultaneous resets of all three FCMs, which could result in flight control surfaces not moving in response to flight crew inputs for a short time and consequent temporary loss of controllability; and to address potential unannunciated dual symmetric inboard slat skew, which can result in adverse handling characteristics of the aircraft.
B. There are three approved...

Could this be a case of LATAM not following up on this AD relating to a fault in the B787 FCM? :
Federal Register :: Airworthiness Directives; The Boeing Company Airplanes
As I understand it, the AD (originally issued in 2016) requires 787 operators to reboot the FCM every couple of weeks because otherwise it'll eventually experience some kind of buffer overflow resulting in spuriously low airspeed data causing it to push the nose steeply down to correct a perceived stall? I have no doubt Boeing issued a fix, but perhaps LATAM hasn't installed it? The expected outcome does seem to closely match the unconfirmed pilot reports of what happened.
UPDATE: The article below however refers to a potentially more serious problem (as if this weren't bad enough already) in which power to the flight deck instruments is also lost if the aircraft's systems are not rebooted at least once every 240 days. I'm curious to know if the flight crew reported a sudden...

Blancolirio, using data from flightradar24, believes the pilot tried to turn hard right from the end of the runway onto taxiway SC with a ground speed of somewhere between 20 and 25 knots.

United B737 MAX 8 suffers gear collapse after landing at IAH
It's not clear if the gear collapse caused the runway excursion or vice versa. Hopefully more info soon.

Final Report in English: 1 (caapakistan.com.pk)
The comment in the Executive Summary stating "Owing to an un-precedent (sic) combination of technical malfunctions, this accident proved to be a unique case" is at best misleading, at worst an attempt to cover-up or deflect from the real cause. IMHO the violation of the sterile cockpit rule and the prolonged unresponsiveness of the flight crew at the start of the approach should feature prominently in the Executive Summary.
