The market (correctly) assumes that the FAA won't make any decisions that might endanger Boeing financially in any really significant way that might turn into an existential threat.

Also true! And if the mood strikes the media complex to kick a wounded gazelle for profit, which they are known to do, a site like this getting featured on the news may well feed back into their stock price too.

And moreso than passenger complaints. Passengers don't buy airplanes.

Boing will listen to the airlines and the markets.
