The Internet has made copyright law outdated. Social norms are in the process of adjusting to the new situation. It’s perfectly rational and normal for activists to hasten that process by defying the law, and encouraging others to do likewise. Obviously, the copyright lobby will react by trying to strengthen the laws, and step up enforcement. That’s fair enough too.
Which side will win? Well opinions vary, but to suggest that breaking the law is in itself an immoral and irredeemable act, is naive.
