I think you overestimate how much the average traveler who may die when parts fall off cares or is parsing whether it's Boeing's mistake or Delta's. What I'm taking from the headline (we need to get our shit together before a bunch of people die) is different than what you seem to be worried about people taking from the headline.

There were passengers on the flight. I would feel highly uncomfortable after this incident to be on another plane of Delta.

I'm pretty sure nearly every such incident is reported on in the news.

Now, is it being spread far more due to everything else going on? Sure. But I don't see why this headline would be weird if nothing else happened with Boeing recently.

It has been this way for decades. Literally decades. It's not anything to do with making Boeing look bad or good. It's everything to do with the model of plane. Airbus planes back in the day had catastrophic hull failures.
