Many people have "claimed" to be founders of Anonymous, but the reality is there are no founders, because Anonymous is supposedly an idea. Anyone can claim to be a leader or a hacktivist, or whatever you want to be. Think of Anonymous as an MMORPG, you create a character, you find something you're good at, you find a guild that has others that are good at the same thing you do, and then you go find targets. 90% of Anonymous are fanboys, 5% are hacktivists/hackers. I think some of the things they do are good, and I think because they allow such a broad range of members in, they can do a lot of bad.
I like it when they go after pedophiles and human traffickers, the sub-group that do that are good people, mostly former law enforcement and PIs. They have connections within certain jurisdictions to give leads. I don't care too much about the Antifa branch, I think they're true purpose is lost and they've assimilated whatever social cause is trending at the moment.
