As time goes on, I feel there will be vanishingly smaller numbers of people that remember "Anonymous" was just a bunch of teenagers from 4chan's /b/, and that it was never really an organization, but a default name given to posters.
I thought the same thing when the article called them an "activist group", and called the guy on the youtube video "a representative" of the "group".
While this feels great, I worry if this is a good idea to threaten ISIS on behalf of the French government without the French government's backing or approval. I like that Anonymous is taking a stand against these attacks, but worry about their plans clashing with the governments. And maybe the boasting is unnecessarily going to invigorate ISIS. I wish they would just simply declare cyber war against them, then take them out, and boast afterwards.
