He got jailed for something in a way that trampled on his rights, he shouldn't have been jailed in that way, a judge agreed and set him free.
But the real damage he caused (rather than alerting AT&T in a dumb way that their security sucks) is that he tried very hard to ruin some people's lives, and that he succeeded to some extent in doing this. That he rejoiced in their pain and then tried very hard to pretend it wasn't him is despicable (and makes him a cowards besides being an asshole) and I wouldn't mind if someone directly harmed by him sued him for that and if he went to jail for that.
Does that clear it up for you?
