Well yes, although it's possible the Ethiopian Air pilots haven't seen that memo. If I recall correctly, a fast remediation suggestion was to switch off all avionics power. As a pilot myself, I would be deeply reluctant to do such a drastic move, especially in an emergency. With the airplane in an overpowering dive, removing all instrumentation in one kill switch move just doesn't seem like the right thing to do. While I don't know the 737 MAX 8 electrical layout, in small planes that would also kill the radios, transponder, and navigation systems, possibly also flap controls, lighting, and some direct instrumentation. Such direction would have to be very strongly communicated if it were a viable escape from the MCAS/AoA failure.
