I guess Martin1234, the difference is that we must keep to speculation, and avoid defamation or slander.
It is one thing to speculate as to what might have happened and another to say, "The crewchief/pilot/manager/passenger was/is a known jerk/felon/incompetant/murderer and that's why the accident happened." Those statements are not speculation, they are outright slander. It is possibly bad form, probably actionable, and certainly not defensible from someone who is now dead.
My thoughts are to those lost, and to those among the company, regulators and manufacturers who now are working hard to understand this one so as to prevent a next one.
