Harry, I do understand your frustration. But how would you be able to identify those downloaders who need to pay their fair share to you (except from the one who is shouting it from the rooftops) unless further (non-copyright) legislation is passed that will seriously restrict our online privacy?
And then there is also the ''public opinion''. Why would so many people never steal a CD with your software from a shop but see no problems with downloading it for free? Because for most people downloading does not ''feel'' wrong, whereas stealing a CD does. That''s not easy to change. And consequently, politicians who would dare to propagate the ''better methods'' you want should fear for their career in the next elections.
