Some folks seem to have forgotten the 737 MAX's MCAS flight control software systems, which killed nearly 350 people, due to Boeing not wishing to train pilots on this system, much less even mention this software's mere existence, in order to maximize profits.
There was no Maintenance (or lack of) that could be conveniently blamed on the purchasers; try as Boeing might, or to blame it on "Pilot Error".
Further recent events, red herring, small potatoes and "both-siding" aside, there is a documented culture of profit over safety at the "new" Boeing.
