When talking about "instrument-rated", this most likely means a real rating certification. As for the flight simulators, best class "Full Flight Simulators" actually allow for zero "real" flight time for type rating transfers, as well as being actually used for the required regular training of airline pilots (per https://en.wikipedia.org/wiki/Full_flight_simulator)
It is a real thing, but he's not type rated on a 737 and it shows. He and eetimes get a number of things plainly wrong. The article was mostly content-free clickbait and I'd encourage you to simply flag it.

The elephant in the room is not the type-rating issue so much as the speculative cause of the crashes: if your aircraft is out-of-trim and control pressure cannot restore it, you have a runaway trim condition and you need to disable the electric trim system immediately.
If, in these cases, it turns out that the AOA sensor was faulty, that is only one of many possible causes for a runaway trim condition.
The core problem is not the specific cause, but the failure of pilots to respond appropriately to a common and easily-remedied situation.
