Yes, the controlling pilots for both AF and QZ made hard to explain inputs after losing spatial awareness. The question why was this not over-ruled by PIC was never answered sufficiently. Reading the QZ report in this respect is heart-stopping.
The take-over button only works when you use it, again your note on incompentece are true. Yet the intuitiveness is galaxies apart if you need to correct. Airbus pilots (LHS+) are trained to cope but are they proficient in using the button? What means are there to achieve and maintain such skill? Is it understood that teaching the "I have controls" call and press the button (per FCOM/FCTM) is negative training?
If I can add my 2c...
It is up to ATOs and Operators to establish training policies and procedures in such a way that pilots are and remain proficient with the proper takeover technique. It is important to clear bad habits and insist on the usage of the proper technique which can be practiced during simulator sessions with the instructor occupying the other pilot seat. In my company the flight safety team has a very pragmatic and common-sensed based approach on event management
but "dual inputs" are highly not tolerated (like an unstable below 500ft), including during training flights, because it can lead to very serious events.
