So I think the discussion should be about the copyright law. Not about "I think this service sucks so I will get an illegal copy".
Don't get me wrong. I think it's absurd that you can get a penalty of $10.000 for downloading a MP3. I think the copyright rules should change.
But I think it's silly to fight a law by disobeying it. It will give the MPAA good ground to say "see they are pirates".
