That’s certainly true. Deterrence is one of the classic justifications for punishment (and for crimes like this that don’t involve direct violence or specific victims, it’s perhaps the best or most significant justification). But still, the strength of the deterrence is related not just to the specific punishment, but also the likelihood of being caught. I don’t have any data to back this up, but my intuition is that crimes like this of this magnitude are very difficult and thus unlikely to discover and successfully prosecute, especially down to the level of specific engineers. My guess is that this whole situation will provide some deterrence at the large corporation level, but probably not much deterrence at the individual engineer level.
