The ones I have read do not feature three-word explanations, but rather say things like "the chain of events that led to the accident could have been stopped at any of these single points: <seven items> and would also have been stopped if both a&b had been done, or if both c&d, or both c&e" and then discuss how each of the many might be changed. They don't say "five of the links in the event chain were at a profit-hungry corporation, whose CEO should be thrown in gaol, then they'll know to do that differently in the future".

"Runaway corporate greed" is fine reason for a quick and angry post on a social network, but aviation postmortems are a different kind of beast, heavy on analysis and prevention, light on anger.
