Actually, most of what is wrong with Boeing was created by McNerny, who was CEO from 2005-2015.Maybe he has ended up holding the bag for the previous misdeeds.
He had no prior airline experience, and came from Procter & Gamble and 3M.
He’s the one that pushed ahead development of the 737 Max, and cancel the program to build a new midsize airplane.
He’s the one that moved the headquarters out of Seattle, and he’s the one that created the negative corporate culture, and the focus on “shareholder value” over excellence in engineering.
Not realizing that excellence in engineering is what created the shareholder value in the first place.
However, four years is a long time in the life of a company, and when you’re in charge, you are ultimately accountable.
He took over while the 737 Max crisis was ongoing, so it wasn’t new. He had four years to make an impact and he failed to do so.
He was hired to make a difference and he failed to do so.
So, yes, he is responsible for a lot of Boeing‘s current failures because he was brought in to fix them.
