That is were the terms black hats and grey hats come from. I assume there are even white hats, guys who make stuff, grey hats who take it apart for fun, often violating law but not liberty. Speaking of Hams, I passed my technician exam on Sunday. I can see the similarities, but many hams are not Hats of any color, more people with spare time that are interest in tech that can connect a world without buying airwaves from government.
