Actually the stall protection could not be countered by the sidestick in normal law. The pilots switched off two of the three ADRs giving them alternate law without stall protection (just speed stability).
This was at that point not a published procedure and it is very likely that lesser pilots with no technical backup from the company would not have successfully completed the flight.
Having said that, a 3 out of 2 voting system is vastly superior to alternating between AOA 1 and 2 as Boeing has done with MCAS.
