It is official it's just that it's membership and leadership isn't.
Anonymous is basically just a mask for greyhats to operate under when attacking targets who can backlash more specific groups.
Would not be surprised at all if some anonymous hacks were committed by already known hacker collectives who knew they had something big but wanted to avoid retaliation.
I prefer the term "hacker activists" which can include blackhats, greyhats, and sometimes whitehats that get angry enough that, even if they do not actively participate in an attack, they can provide resources of all sorts.
There never was, all the way back to day one. Any given "operation" may or may not have overlapped in membership. The name is literal, and always has been; but with it comes a set of meanings and tropes (the mask, "we will not forgive, we will not forget, we are legion") that a given actor taking the name can invoke as a call to action for others, or use to simply mask their identity.
How are they defending OP in any way in this context and also how the fuck is having a single 'magazine' that's dead and not filled with bot propaganda spam ?
