No, it doesn't. See, this is what happens when you start talking about crimes on the internet when you really shouldn't be. If I leave all my doors and windows opened, or if I put a box of valuables in the middle of an empty lot that I own, it doesn't suddenly make it legal for people to steal from me.
AT&T leaving their doors and windows open does not suddenly authorize any ol' grody troll to walk in and take personal information.
Whether you like it or not, his crime will be made into a physical analogy.
