If you actually believe in the moral correctness of the law being used, I don't think that's actually wrong, is it? "You are breaking this law. You and I will both spend a bunch of money getting the courts to stop you from doing it. Instead, you can choose to stop doing it and settle with my firm for the cost of tracking you down, which is strictly preferable for everyone involved."
(I hold this opinion weakly, so please argue me out of it if it's dumb.)
