one fun factoid in favor of your argument is that Latin American drug cartels have been known to build their own submarines for drug smuggling. however, most known criminal dev teams are hacker groups in Russia who either operate as part of official espionage activities, or are allowed to operate as long as their victims aren't Russian. all that being said, though, this "criminal software" idea probably isn't as true as you think. criminal enterprises are inherently risky, and there's so much money to be made in software that anybody good enough to do well in a criminal enterprise could do well normally. (unless we count normal companies which get away with breaking the law in the course of normal business as criminal organizations — e.g., Amazon and Tesla for union-busting — in which case, there are probably a lot of people reading this who technically belong to criminal organizations, although some percentage of them would intend otherwise.)
