Autotrim did not put the aircraft in unrecoverable stall, the PIC did by continuing to pull up. If the PIC (or PNF) held the stick forward for as little as 8 seconds the autotrim would have rolled the THS forward and *aided* the recovery. Not only that, but if the crew had levelled off at any point prior to the apogee of the zoom climb, the autotrim would have stopped the THS then and there.
People can argue back and forth over systems understanding till the cows come home, but the 800lb gorilla in the room will always be that the PIC responded to a transient UAS problem by pulling up, continuing to pull up through the resulting zoom climb and continuing to pull up through the stall - and that's before we get to the stunning lack of CRM during the sequence.
