I've heard a few pretty good theories, including some articles posted here. By "good", I mean they make sense; I can see the mechanism by which the cause causes the effect. "Woke" isn't one of them. My God, everything bad is caused by woke. Remember the wokeism that caused the ship to hit the bridge in Baltimore? Remember the wokeism that caused the plane crash in DC? That is mind-numbingly stupid. By the way, Boeing is headquartered in VA, not "woke" Seattle.
One good theory that I have heard is that management decoupled from engineering and operations when they moved HQ to Chicago and then VA. Now that doesn't mean the move caused the decoupling, rather it was part of the decoupling. They lost focus on building good planes. Hopefully they can "couple" again. America needs it.
Full disclosure: My opinion certainly has some unconscious bias. In my case, it is the bias of an engineer who has been in development and manufacturing for over 30 years.
