And they charged the corporation. They also have a consent decree. You can be sure that under the consent decree both the corporation and everyone in it are under a microscope. A consent decree is, among other things, like probation. If they mess up again, the DOJ will drop the hammer.
A lot of people seem to think that punishment makes people care more somehow, but punishment is always a distant possibility at the time of the wrongdoing. People don't generally think they are committing serious wrongdoing, humans are really good at rationalizing our actions, especially when each individual action is a small step.
The CEO has enough power to prevent such a thing from ever happening (by that I mean he can easily create a morally corrupt company culture) and there is a very big profit motive to do so.
If middle managers and top engineers see that there is no reward in doing things right and taking time, in fact its shooting one's foot, then most folks +-align with this policy and move on. At the end almost everybody is in for the paycheck.
That fortunately doesn't matter.
To send someone to jail, you need to convince a jury they committed a serious crime.
Sure. My point is that it's quite different from a conviction.
If the CEO goes to prison, other CEOs will care more than this one, if some compliance officer does, the next one won't be as willing to bend to implied pressure from leadership.
