Anonymous is the best that could ever happen for proponents of a crackdown on freedom (through/via/on the internet). No one knows who's behind it, so no one will stand up for them, no one will complain if they get harassed and all the blaim for everything that goes wrong in the future goes to Anon/hackers. It's the perfect scapegoat for incompetence.
Or like "save the children" isn't the political slogan which always has been, and always will be, used to justify anything.
I am not sure if LuLzSec is good or bad, or a wash, in terms of how politician will use them. It does not really matter, politicians will use anything and nothing to get what they want.
But this BBC coverage is surprisingly fair. And if coverage like this becomes the norm, who knows LulzSec might actually be good for the public image of what anonymous hackers on the internet are.
