But...it's the pilots' faults, right? Wasn't that the consensus from the experts, the last I checked the last thead on it? The pilots didn't knowhow to shut off the auto-pilot and do a manual trim with that wheel thing. Not the plane's fault.

As I understood it........
The manual trim wheel is not usable due force required to move it, on prior models when auto trim/computer circuit breaker was 'off' the pilots powerassisted trim from yoke switch worked - in the MAX this switch was made to be unpowered forcing use of manual trim wheel which of course wasunusable.
Besides simple fact that reducing power in stall condition is about the most un-natural thing to do! which is whats partly required to stabilizeflight due engine position.
Bad design outright for a passenger aircraft.

In 2016 (as a response to the Airbus A320 NEO), Boeing introduced the ‘MAX’ series – designated MAX-7, MAX-8, MAX-9, MAX-10, MAX-200. The MAX-8 was the first to enter service – in 2017. The MAX variants offer four lengths, with options for 138 to 230 seats and a range of between 3,215 and 3,825 nautical miles. Disaster might have been easily averted should the 737 Max had the autopilot cutout switch so that MCAS or a misunderstood automated flight control could be disabled without requiring manual trim wheel operation, and retaining thumb switch control. Note how the trim wheel moves continuously (the trim wheel on the 737 moves much more rapidly than it does in my Cessna, FYI). That’s what happens when there’s a short. It just runs and runs.

Hi Centaurus, From what I remember of the B707-320 over 40 years ago, the possible scenario of the HS refusing to move when under high aerodynamic load could apply to electric trimming (using the piccolo switches) as well as manual trimming (cranking the large trim wheels on each side of the centre pedestal).
