I don't think we need to dig into specific technicalities of this, especially with our limited knowledge of the hidden, behind-the-curtain power structures. This law was specifically designed to create an internet weapon of suppression of the unwanted. Apple could have use this to suppress jail breaking. Microsoft could use this to suppress Linux. Lobbyists could use this to suppress the Occupy movement. The powers that be as such could use this to destroy the power internet gives to people, first time in history. However for some reason, they have miscalculated - they did not expect this kind of organization, backlash and opposition. Now they are just trying to distance themselves to save what's left of their images.

The reason why they miscalculated is a mystery to me, perhaps they have realized they have let this "internet" thing go way too far, they cannot control it anymore using controlled disinformation techniques, and this was one of their last attempts to stop this trend.

Yes, it's really that bad out there. But it's getting better.
