Blaming the Ethiopian pilots (One of the safest airlines in the world btw) for getting over speed during the workload induced by runaway trim is disrespectful.
By now, near every professional pilot agrees that these are near unrecoverable events unless you assess and cut the trim in first 15 seconds or so.
Blaming Lion Air in the first hours after the crash, with their somewhat sketchy history, was understandable.
Everything after that is uninformed or racist.
