Yeah the fault is at Boeing but not like they do this kind of videos, or if they do most people wouldn't have seen them.
And I don’t see how lighting a fire under the wrong entity’s ass helps anyone other than Boeing.
Alaska has been lax in maintenance before (critically so, e.g., https://en.wikipedia.org/wiki/Alaska_Airlines_Flight_261). If this pressure flows through to Boeing than so be it.
I do agree that it would have been better to skewer Boeing directly but I can see why they chose the path they did.
