I agree on the quality of the description, but only to a certain point. I think that neglecting to state that their actions are largely retaliatory could have been used to not-too-subtly tinge them as "pranksters" rather than "activists".

As far as I know most of them could well be within the former cateogory, but their most visible attacks were not enacted "just for the lulz"; rather, they were guerrilla tactics employed in response to perceived threats to their Internet homeland, as stated in above comments.
