Certainly some email does (expose political corruption and influence peddling), for sure. And if we published all email of every person everywhere, then we'd uncover a whole lot more.

Do you think we should do that? Where is the line?

There is no line, any line would be simply arbitrary.

If you get your email stolen and the people who got access to it found out you were doing some illegal activities, then it would be irresponsible not to publish your email to expose those illegal activities, especially if you are a Fortune 500 company.

The line has been made so that those with the power to throw us in cages already have that info. I would say that publishing the info of the far more powerful so that the far less powerful can see it is a far lesser issue. You are asking if we should draw the line at 10 meters or 11, while it has already been drawn at 20 km.

If you have nothing to hide you shouldn't be worried, right?

Until the government protects the privacy of digital correspondence this should continue until we know all of the dirty little secrets our governments and corporations are hiding.

And as other commenters have said, none of the individuals caught up in this should have had an expectation of privacy anyway. The IT dept of Sony could have already accessed this info, and it's theirs anyway.

Like if your money gets stolen out of the bank.
