What I am suggesting is, there are more tech ways to move the pitch control surfaces, than only the yoke and trim switches itself. Having an open mind to these aspects might be useful, instead of diving onto a suicide scenario.
You are missing the point. The leak suggested the "plane did what it was told to by someone in the cockpit". That would rule out runaway trim in my opinion. I will concede, the leak is no more reliable than a paper tissue condom.
Either way, runaway trim has a memory item drill. Given the demise of the Max, I'd have thought any Boeing crews would be pretty hot on that.
