Which is why Occam says it’s far more plausible that sudden impact caused the ACARS to stop sending data than any human act. Especially since one was received after 5 hours.

ACARS was disabled early in the flight. Malaysia doesn’t subscribe to the full reporting ACARS anyway.

The supplemental engine condition telemetry that goes to Rolls-Royce by satellite is what was broadcasting about every 30 minutes for the rest of the flight. That ended when the flight ended.
