On a basic level, perhaps a more critical look at the parameters of autopilot in Turbulence? Any situation which presents as requiring manual handling should originate a loss of autopilot and reversion to manual flight. Not only UAS.
We here have consistently exonerated the use of Autopilot in this turbulence.
The pilots admitted they were entering cloud, but more important is the assumed icing up of all three pitots. Of course they were in cloud.
