Let me put my home entertainment gear in the back of an open truck and park it in a bad part of Detroit while I go eat lunch in a restaurant.
Now tell me how I'm not, in some part, to blame when I get back and all of the electronics are gone.
They did not leave the truck open. They entered a password, answered the security questions. That's it. It's like blaming someone telling him that the electronic had been stolen because the window's glass was not bullet proof.
Dude, it's not that they shot their private version of 2girls1cup and put it on a non-public youtube channel. They put some private pictures on a private, protected backup server.
