The stick shaker is driven from the angle-of-attack system, not airspeed, because that's the least difference between physical world (the wing stalls at an angle of attack, not an airspeed). In this case, the differential stick shaker may have provided an additional clue to the crew. While I'm generally critical of the crew training and performance, particularly the Ethiopian Air crew, even I can't reasonably hang missing the differential shaker indication on the crew.
Your last paragraph raises an excellent point, and one which points to the need to put fully trained, but equally importantly fully seasoned, crews into large transport aircraft in passenger service.
(some) People in aviation cried about the implementation of the 1500 hour requirement to get an ATP (Airline Transport Pilot) certificate after the Colgan Air crash in Buffalo. To me, these two accidents [and others outside of US/Western European carriers] show the wisdom in that decision, especially the most recent one. I have right on either side of 1500 hours (all but 20 in piston airplanes, about 4 hours in 737 level D sim) over a 21 year span. If I went to and passed a type rating school now, I'd hold myself barely qualified to do the walkaround when it's raining, sit right seat, run the radios, carry the captain's bag, and eat whichever meal she didn't want.
350 hours is not an appropriate time (IMO) to have a front-seat position in a transport jet flying passengers.
