Maybe I'm being dense, but I don't get the point of this article. If the Church of Scientology owned a significant share of Time Warner, then there would be some irony. Or maybe I missed it and Anyonmous is an anti-capitalist organization?
Frankly, I think this is the right mask to use. It is consistent with the role the mask portrayed in the movie V for Vendetta. Further, this image is mostly free of the negative political implications of just about any other mask (e.g.: Imagine in Anyonmous used a Richard Nixon mask... they'd look like bank robbers or the topic of richard nixon would muddy the waters. Nobody is debating Guy Fawkes when they see people in the mask, because the mask is the supposed to be a mask and the original mask wearer was using it as a symbol of fawkes protest, not fawkes politics, etc.)
