Trying to "remove the pilot from the equation" is exactly what caused this crash, by giving primacy to this automatic trim adjustment system over the pilot's control inputs. We need to design systems that are more respectful of the pilot's input (in particular, that respond to the pilot's obvious intent rather than requiring the pilot to use some unusual cutout switch to achieve the most basic aeroplane functionality of: push stick forward => pitch down and vice versa).

I'd consider that even more dangerous. Stick pushers actually activate before the plane stalls. These large aircraft are designed in a way that a full stall could be catastrophic. Stick shaker events (the thing that happens before the stick pusher) happen quite frequently due to pilot inattention. In this case, an accident occurred, however, more frequently, they save lives.

A traditional stick pusher is a much better design: the pilot has clear visibility into what's happening, they can see that the plane is pitching down because the stick is being pushed forward. Pilots do make mistakes but so do automated systems; the way forward is to build systems that collaborate with the pilot rather than cutting the pilot out.
