I think the satellite data *could* refer to any ACARS maintenance information transmitted to Boeing and/or GE and/or Ethiopian. Just like the AF accident, there were ample maintenance fault messages received well before the FDR was recovered that might have given the precipitation of events
Regarding the larger picture here, an average crew, newly aware of the newly-revised MCAS ‘warnings’ could still be easily saturated by stick-shaker, air data miscomps, and ever-increasing stick forces in that scenario.
Disconect stab trim trim, pitch and power for a safe climb-away...may have been too much for a crew of certain caliber. Simulator training may have mitigated an accident of an afflicted crew, but time will tell what went wrong, and how.
