I would be disgusted if they did. It's private information. Just because someone stole it and made it public doesn't mean you should propagate it further.
I don't think that's possible. It's too integral. Think about communications you make that are intended to be private between you and the person receiving it (your doctor, the government). No matter how important the communication I think in 10-20 years there will be no option to snail mail that. Snail mail could be 'hacked' much easier but there are laws in place to prosecute people for violating that expected privacy. The same thing should happen with communications online. Of course this all depends on your views on privacy. I believe privacy is a essential right, one which we must defend or there will be severe consequences. It's very difficult to do that online but just saying 'anything you post online should be considered public' erodes privacy rights massively as it is such an important communications mechanism.
If my info (I'm not muslim) was leaked in a dump I wouldn't care if some intern in an office somewhere went through it to find something useful as long as long as a large fraction of it isn't published all together.
Regardless, I expect the staff of the various network evening comedy shows to be combing through this for raw material and will be disappointed if (after this hits mainstream media) those shows don't throw around some politically incorrect jokes.
edit: my comment was misinterpreted. I meant jokes along the lines of "this guy is very religious, went to school in $place" -> take some words out of context -> some joke about stereotypical thing about $place"
I did not mean to imply that they'd just read funny excerpts of people's conversations, take them out of context and then tell everyone who said it.
