Because Anonymous isn't a group to rely on,Anonymous can't be even called a group,its just random hackers getting together,not just one such meeting but multiple ones.Anyone can put up a guy fawkes mask/Anon BG picture,with voice tearer and make speeches.That's why Anon videos on youtube or statements on any news site condract themselves more often than not.
Anonymous is nothing but a title for someone whos behind multiple proxies,who are randomly in possession of a fawkes mask.There's no official spokesman for Anonymous,so whatever the news feeds claim to have squeezed out of them matters not and is bullshit anyway.
It was originally just a name for douches which do XXL trolling,originating from 4chan.
Anonymous were never something most would call ''freedom fighters'',sure they were there protesting against Scientology but at the same time there where people with the same name encouraging Scientologys method for shit and giggles.
