Devil's advocate
In Sweden, PRQ/PiratByran are actually quite appreciated by the populace as they are kind of playing Devil's Advocate against overreaching laws and taking advantage of various countries' more liberal systems. In a big way they're saying "Look! We're pirating software en-masse! Is it destroying the world ? No!"
Others have pointed it out already: Pedophilia is not the same child abuse. Being attracted/aroused by children and acting upon those urges are two very different things, the same as a hormonal/tempermental guy like me can think about acting (extremely) violently, yet I can keep it under control and live a normal life.
If anything, having an open forum to discuss controversial issues can be a good outlet for people to get educated on the topic, and maybe even help deal with it. Many pedophiles know they're messed up, but society's knee-jerk approach makes it practically impossible for them to talk about it without being lynched. It's a bit like the mental anguish suffered by in-the-closet homosexuals, who don't know who they can trust with their innermost thoughts.
As long as PRQ doesn't let this devolve into something abusive, I'll back them up. Those fellows are some very smart cookies!
