Remember, the person who oversaw the start of the changes was a Boeing lifer - by the time Condit left due to corruption scandal caused by his subordinates and let an ex-McD-D executive in, he had already initiated outsourcing strategy and the idea that Boeing was to concentrate only on "final integration", changed the HQ, and set goals and rules for 7E7 (today's 787) project including ridiculous cost cuts (the project, which used completely new technologies for Boeing, was supposed to cost 1/4th of 777!)
You can convincingly argue that Mac did make the MAX and Mac did oversee a process where planes flew without doors bolted on, because Boeing no longer exists. It's just Mac wearing Boeing's branding and facilites like a skin suit.
