Anonymous was a household brand name during Obama as they were exposing a lot of what he was doing behind the scenes, like drone strikes on innocent civilians and illegally targeting Americans overseas without due process. It was in the news constantly with their videos at a time when most people still watched TV.
You never know whether Anonymous is one angry teenager or an entire nation-state, so it behooves you to not piss "them" off.
I don't know who the current owner is but it's certainly not to be trusted by any hacktivist.
Edit: Another owner of the YourAnonNews account was Dan Stuckey, a Vice journalist, who was the one affiliating with Sabu[1]. Him and Dell operated the account for a long time, maybe they still do.

Bah, no you're not; you just hacked that.
If you're a fan of the Wichowski Siblings then you may recall the quote "You cannot kill an idea" from V for Vendetta (and also the silly mask). They use this to demonstrate and inspire the power of cellular, decentralized activism.
I'm confused by this, are you referring to Lulzsec specifically? I've never heard Anonymous framed as leftist, and I'm certain that not everyone involved in pre-2011 hacktivism, such as Project Chanology[0], are in prison.
But OP is probably confusing these shenanigans with Lulzsec, an supposed anonymous hacker collective but really FBI-led operation ran by their informant Sabu, who supplied hacktivists with targets to hack and later jail them (for example Jeremy Hammond who was sentenced to 10 years in prison because of this).
