Apparently the copyright of web pages behind a pay wall. Blocking the domain causes their pay wall to not work - they probably load pay wall scripts from there - and allows unauthorized users to view their client's page without compensating them. It's similar to having a movie theater with a locked door. We want to see the movie, but we don't want to pay, and distributing lock picking tools is illegal. And their door is "designed to only stay locked when a light is shining on it". Here again, we are using technology to disrupt old laws.
