I just have a hard time with Boeing not keeping the manual electric trim operating when MCAS does its trick.

I suspect gums was referring to the change in the trim cutout switches from NG > MAX, likely he meant pilot thumb switch trim by 'manual electric trim'

NG one switch disables all automatic trim inputs, the other disables ALL including pilot electric trim inputs.

MAX either switch disables ALL electric trim.

Reverting to the NG configuration 'might' be one way out of the stuck trim question.
