I am not sure that I am uncomfortable with that. If you are using AT&T's network to commit abuse then you are disrupting the usefulness of that network.
I think that the equivalent would be if you committed fraud using the postal system the postal service being able to take legal action against you.
I'm very uncomfortable with the criminal aspects of cfaa (US government vs Joe Small Man) but I think I'm ok with civil cases as long as we agree that we are not into boats.
True. Though I can see some situations where the criminal aspects would be acceptable. Such as a case where hacking was the proximate cause of catastrophic harm (like a criminal using an insecure industrial control system to crash a power grid).
I am almost willing to support criminal aspects in this case. Extrajudicial killing was a predictable result in giving these tools to repressive governments.
