Edit: so many angry reactions. I was answering to a post that seem to hold the point that it wouldn't be a scandal, if a multinational company buys influence from politics. With this I indeed disagree.
What your comments suggest is that I think it is ok to publish illegally hacked material. I don't and I did not write that.
On the other hand I have some trust in wikileaks that they don't publish the data just for everybody to sneak into private affairs. I expect it to contain proof of illegal action. That's now for journalists and investigators to find out.
But there is still the issue of illegally acquired data. Where I come from, this must not even be used in court and thus would be worthless.
