I'm sorry, but I have to politely take issue here. I see that sentiment (regarding Anon and Guy Fawkes masks in general) parroted all over the internet, and it's really starting to wear on me. Ignoring the fact that V for Vendetta was a far more nuanced comic before it was a thinly veiled American political allegory and that most non-Brits wouldn't even be aware of the irony of Anon using Fawkes masks for symbols if it wasn't for a few snarky humor sites pointing it out, it's still kind of a hollow point to make.
Most of the holidays celebrated in the western world today bear almost no functional resemblance to their actual historical roots. Handshakes and toasts, by some accounts, were originally just as representory of mutual distrust as they were of fellowship. At one point, the swastika was a sacred emblem of good fortune for cultures the world over. Symbols have whatever meaning the people at large charge them with, no more or less. It seems sort of finicky to take issue with a group over what they choose to represent them.
As to the content of the message itself, the man doesn't seem to be saying anything particularly groundbreaking or powerful, but he's not wrong on any given point.
