The ultimate factor was a stall with a botched recovery.
While "mode confusion" may be a sound analysis, I will point out to you that, based on available evidence, there was no attempt at stall recovery, therefore one cannot have been botched. Why do I conclude that? There was, based on available evidence, not recognition of stall from which to recover, even though one was in progress.
There was a botched response to a malfunction, that led to a stall.
After that, I think you can argue that mode confusion was the
modus operandi until impact with the ocean.
