Those emails we're exposed to the public. Weev's security company exposed "gaping holes". AT&T are at fault for exposing their customers information in the first place.
Anybody COULD have done harm with those emails. He didn't. He used them as a fodder for public discussion about internet security.
AT&T should owe him a "thank you".
AT&T customers owe AT&T a boycott for being irresponsible with their information.
