The problem is that while most of us agree, we all also know that isn't how the world works. IA is a major name, they are obviously not operating under the radar. They picked a fight they weren't ready to take on and they should've known better, but instead they decided to jeopardize the entire project.
If you want to be The Pirate Bay, then you need to play it smart like The Pirate Bay. This was reckless and short sighted.
