I blackmail my kids all the time... ("Wash your hands after using the bathroom or you will put 25 cents in this jar")
I was actually marveling at how precise the wording is in this piece. Curious how different these things can come across.
Calling someone "a criminal", meanwhile, degrades their status to that of a common mugger; someone in the lower class who needs to commit crime to survive, and who doesn't have the intelligence required to come up with a clever crime.
Hackers are generally aesthetes--we tend to value our intelligence, curiosity, etc. more than we value our moral fibre. We can appreciate stories like "A hacked into B to see if it was possible, and reported the vulnerability all responsible-like, but then they threw him in jail! How horrible!" because we think the positive-status from the display of intelligence makes it less likely, rather than more, that they were genuinely seeking to harm the people they hacked.
Because of this, I think we here are scared of being potentially associated with dumb, low-status, lower-class criminals more than we are of just being considered evil. People hire "evil, black-hat" hackers. Nobody hires a dumb hacker.
There is moral judgement involved with calling someone a criminal, and rightfully so. Taking what other people have created by force or extortion degrades society.
