Thank you Anonymous for admitting that you are criminals.
You're a criminal too, you know.
Ever watched a DVD on Linux?
Ever downloaded anything?
Ever sung a few lines from a song in public?
Two of those are crimes punishable by a 250,000 dollar fine and possible jail time; the last one is simply a civil matter which can net rights-holders upwards of that quarter-million depending on how many songs you sung and how the jury's feeling.
I'm not trying to change or hide the fact that DDoS attacks are criminal; and they will continue to be for the forseeable (10-30 years) future while the current crop of technology-dumb politicians die off. After that, I expect things to change- just like I expect the DMCA to be repealed at that time (there will be something else after that though).
But the thing is that there are only certain ways to protest against a company or five that are trying to take away your freedoms; that way is online. You can't assemble many people who don't have much money to go halfway around the world (or even just the US)- so you protest in the only way you can, which in this case is online.
But that's just talking about DDoS, which forms the majority of Anonymous' operations beside the usual trolling, raids, and other Internet jokes.
I have no moral problems about joining 100,000 other people in burying a site in ping or ACK requests; that protest is usually broken up quickly and doesn't do any irreparable harm to the company you protest against.
But I DO have a problem with actually accessing a server-side computer and changing files; it's like taking down a business's poster from the inside of the shop by breaking and entering. If it's illegal to do in the physical world it should be illegal to do in digital and vice versa (something Anon fights to protect in their own strange ways).
But that's not the typical news-making operation against anti-1st-amendment target X which should be allowed to take place.
