This is incredibly naive. We are talking about a company that was literally too lazy to check if all the bolts were in place and secured in an airplane, risking a fatal incident with hundreds of people killed. And that is after two planes already force crashed killing everyone on board, because of a faulty IT system that was not properly checked.

Boeing has proven plenty, that they have a full disregard for human lifes, if they think they can get away with it. So assassinating whistleblowers and using their influential friends to cover it up as opposed to uncertain and lengthy court battles requiring millions to be spent on it, is absolutely in character.

Again that character was to ignore safety warnings, despite knowing that sooner or later a plane will crash and it will cause a shit ton of damages to the airlines and it will cause a shit ton of litigation towards Boeing. It was by far the obviously cheaper choice to just do proper QA. They have neither a moral nor a long term profit/investment outlook on humans lifes. All they care for is immediate profits.
