You should blame the people who made the leaks necessary, not the people doing the leak. Again, manipulating the data in anyway undermines their legitimacy.

I'm not sure it ever was "necessary" for Wikileaks to indiscriminately release large collections of emails sent to the Turkish government, especially if the HuffPo report is correct and it pertains largely to ordinary citizens' messages.

"If you have nothing to hide, you have nothing to fear" is even less true of releasing citizens' sensitive information to the entire world (including factions in a country where people are being killed over their political actions) than it is of allowing governments to collect and share it.

Just because some of the things revealed by Wikileaks are very much in the public interest doesn't make it an entirely benign actor.

If the data exists it may get leaked. It's up to people to protect themselves through encryption and not messaging bad actors. If someone makes malicious actions post-leak then they should be dealt with. Information wants to be free. There's no fighting it.

How exactly do you plan to police Wikileaks? Twitter shaming? Thankfully they've proven to be immune to that.

What makes a leak "necessary"?

For better or worse, this group believes that practically anything secret should be leaked.

A leak is necessary when it demonstrates the government or the leaders are lying. There's zero democracy when the citizens aren't told what's going on.

But this is not the only information that wikileaks is leaking, so they seem to ascribe to another definition.

Not really, no.

Everything Wikileaks has leaked has been something that shouldn't have been secret.

In some cases we wish it would have stayed secret, but that's our fault (collectively) for breaking our own laws. For instance, had we properly investigated the behavior of our troops in Iraq there wouldn't have been a need to blow the whistle on the situation.

Supposing that the leak is necessary, what makes it necessary to release PII?

I'm sure you've communicated with people who have done things, or work for people who have done things that are necessary to be leaked. Please explain why this means that your PII should be released.

Who defines 'necessity'?
