The moral differentiation is one the author talks about a lot, because it's the usual reaction.

That said; which engineering field are you basing this on? I thought that generally only lead engineers or architects were responsible in that way.

Not sure if this is hyperbole, but usually bugs are caught elsewhere in the design spiral. If caught early enough, this results in a chewing out at worst (I had a bad first job). If caught late enough, this results in a law suit. (Seen it happen from afar)

If you try to hide your bugs, paper over them, and somebody gets killed... that's where the crime comes in... Looking at you Boeing.

Clearly you never owned a german car or a tesla. I doubt anyone went to prison for those

I doubt any engineer at Boeing will go to prison for the engineering of the very deadly Boeing 737 max.
