By your definition, wearing a wig and sunglasses to get away with shoplifting is a "clever exploit." Refusing to put license plates on your car so you cannot be identified for breaking the law is antisocial criminal activity.
Perhaps Jobs' strategy for avoiding license plates was "antisocial criminal activity" and perhaps it wasn't; I'm not a lawyer, and I don't really care - but what does that have to do with the question of whether or not it was a hack?
Of course there's no name.
That's because this is an Internet post, not a car that can be used to maim and kill people.
