Usually corporations tend to act in their own good. Usually, corporations are better and faster at reacting than a government.

Here the problem is executives who are absolutely shit at understanding what the product of their company is (efficiency AND safety). And absolute shit at understanding that yes, you can extract some additional value in short term by reducing standards, but it will eventually catch up with you and the party will be gone.

If I was investor in Boeing I would be screaming to get these executives fired as they obviously are not acting responsibly with good of my long term investment in mind.
