What?

She can do with her Body whatevery she wants. Not just Jennifer Lawrence.
Everyone can do what he wants as long no one else get's hurt.
If she's okay with making private nudies of herself than she can 100% do it.
The Scanal is not that those pictures exist or were made. The existence
of those pictures do not change my view of those women in any way.
About the Privacy of celebrities
Celebrities have a public persona. This Persona interacts with Fans and the Media,
who are still strangers to those celebrities. How much of the Private Person is in this
Persona can vary very much from person to peron. This Persona and the puplic have some
kind of mutual beneficial relationship "celebrity X givs Autographs, Interviews and stuff and
the plublic get's someting to well...like and "identify" with.
But a celebritie's actual privat life? Their actual sexuality? Their fears and most inner thoughts?
Its non of our business. Even if an Actress is nude in front of the camera. It's still something
very different from their actual self beeing nude.
Nothing justifies this violation of privatcy that happend there. Nothing.
The only thing that can be argued about is if it was the smartest thing to
do to have those pics/vids in a cloud. It wasn't dump. I mean those services are
supposed to be save. It would have been smartER to store them on a local
Hard-Drive or USB Stick at their home. But still: It was NOT a "Why the Fuck did she do this?"-Move.
But I think it is like parking your car in a public parking lot that is supposed to be guarded. Yes.
It would be safer to have your car in your garage at home, but maybe it's not possible for some reason.
Noone can blame you to trust a service that's supposed to be save.
It's not like those pics where in some public facebook folder or in an open network.
So who's to blame? The Hacker. He's the only one to blame.
If there was a breach at iCloud Apple also has to take some part of the blame. I doubt that Apple wasn't at least sloppy. But I don't know how much energy the Hacker had to put into this. If he had it easy: Apple is to blame. If you offer a Service it is your responsibilty to make it safe for your customer. If you can't do that, you have to take at least some of the blame.
But in general: Only The Hacker/Thief is to blame. Everything else is in my opinion at least quite cynical.
