The hilarity here is that Anonymous and the FBI had the same target this go-round.
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.
I wouldn't call that "much of Annonymous".
