One of the defining issues that kicked off the Pirate movement was copyright. It was possibly the most defining issue, though post Snowden things look very different now. The web depends on sharing, transmitting, copying. And it was radical that this should be a political issue, not just an obsession for law geeks.
So obviously, it was seen of something of a triumph that Julia Reda MEP was given the task of being Copyright Rapporteur. I'm sure we were all aware of the political danger. Anything too radical would have been ripped apart, not advocating for our views would be a significant failure. It's also true that being in the Green group is where we can get most influence now, they will also hold us back.
