In case you hadn't heard, much of "Anonymous" has been FBI-sponsored activity.
I wouldn't call that "much of Annonymous".
Check the timelines. Some of Lulzsec's most dramatic attacks were carried out with an FBI agent literally looking over Sabu's shoulder.
'Opdarknet' in particular seemed quite a bit different from the rest, in the MO (basically the same as the FBI used against Freedom Hosting) and the wording of their release.
