There are several pilots who've had this very issue happen to them and they managed to diagnose and address the problem without flying the plane into the ground.

These incidents are almost always the result of a combination of errors ranging from negligent engineering and documentation to mechanical defects to human (pilot) error. We simply don't know all the facts in these two crashes.

The publicly available information to me indicates negligent documentation (pilot manuals should have been updated to reflect the new mode and how to treat the issue similarly to runaway trim), negligent sales practice (the AoA disagree feature shouldn't be an option), and poor reactions by the pilots involved. But that's purely speculation at this point: there could very well be some other causes instead of or in addition to these.
