As a start, for keeping details from pilots even after the first crash. For example, after the first crash, Boeing did not disclose that MCAS keeps repeating at 5 second intervals. Surely this was relevant information for pilots in life and death situations. But perhaps it would have required Boeing acknowledging the need for additional training, and corporate greed got the better of their judgement.

The core feature of his strategy for the company was to sacrifice safety in order to increase profits.

It was clear to any truly responsible person that they needed a new design for an aircraft with a fundamentally different mission.

At least one person from the FAA should also go to prison. They failed in their core mission.

This actually seems very similar to a common tactic that managers of software projects will take. Since they are not being judged on the integrity of the code, they are happy to encourage any kind of hack or corner cutting or technical debt in order to save a buck.

In this case the stakes were higher than an average software project and many people died.
