Probably in our first year Aerodynamics lectures we learnt that at high angles of attack aircraft mush along climbing, if at all, nowhere near the attitude at which the fuselage currently presents. This means that strakes on the lower fuselage, best as close as possible to the empenage for maximum leverage, generate a significant nose down force with no crew action and no failure modes. Hence a huge assist to unstall. Details I can't be bothered to find - after 50 years I've likely lost the paperwork. It is not difficult to design a system like this to counter the nacelle lift afflicting the B737 Max.
B737 itself had a problem at high AoA. That's why they deviced STS. When they further tilted the bigger engines to create space underneath it became critical. There were no soft options. So they took the pilot out of the loop and gave complete control to MCAS. But they did it without any redundancy and clandestinely. Airbus has triple redundancy and yet a few problems happened which they sorted out quickly. But Boeing planned the software upgrade in there own sweet time. Unfortunately the whole thing came apart very quickly.
