sharing mp3s is illegal. people still do it. certain software makes it extremely easy to rip and encode mp3s and share it. however, the software you use to share it is not illegal. its how you use the software that makes it illegal. whats wrong with parking in front of a friend's house (as long as they know what you're doing) and checking your email? or parking in front of your own house and syncing up files without having to exit programs and double click this that and the other thing.
hell, shooting people is a criminal offense but i dont see guns being banned anytime soon.
BMWs can go as fast as 155 mph. thats 3 times the speed limit in new york. it doesnt make the car illegal.
