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).
