Totally agree that this is an effort to build the public opinion case for pilot error.
To me the worst part of the 'case for pilot error' is no mention of even the possibility that the crew was unable to manually trim and the suggestion they were very slowly winding the wrong way.
The slight .2 unit wrong way trim during the manual trim phase of the flight could be due either to struggles with the wheel or (less likely in imho) back drive from the extreme load.
He then slams them for the aparent last ditch re-enabling of electric trim.
The lack of speed management certainly was a factor but had they been able to manually trim they would likely dealt with it next.
