Prosecutorial bullying and overreach is bad whoever it is done to (even if they are an Ass/Hitler).
Do you want 10 years to be the normal sentence (or even the prosecutors threat) for crawling URLs and reporting the privacy breaching results to the news media?
In my view some of the behaviour in the story that you linked to is MORE criminal than the actions against AT&T. If evidence can be found for that I would be fully in favour of that prosecution but the he's done all these horrible things that we can't prove so lets trump up a minor issue we can prove concept doesn't feel like a secure route to freedom and justice for anybody. If the linked information could all be proved in court to be Weev I would be happy for him to get 1-2 years in prison for harassment or longer if it is a pattern of behaviour against other people too but for the AT&T "hack" anything over a month or two would seem excessive to me.
