It’s not about avoiding stalls per se, it’s about the uncorrected aerodynamics of the 737 MAX being such that at a certain point it becomes easier to pull into a stall than push away from it.
While pilots learn to avoid stalls, commercial planes are designed deliberately such that at any point short of a stall it always takes less force to avoid one than create one.
Uncorrected, the 737 MAX’s behaviour is a dangerous and surprising deviation from norms. It runs counter to pilot training, and it makes the stall recovery they’re trained to perform significantly more challenging than it would otherwise be. That’s why the FAA rule about column forces exists.
