Let's say the hackers in this situation wanted to prove that Avid Life Media was acting unethically -- that they had lied about wiping old customer data. They could have worked with journalists to demonstrate that without actually leaking personal information to the world at large.
Snowden's critics have claimed that he's put people in danger, but they've never been able to back that claim up with actual examples. And honestly, since they've lied about every aspect of that situation over and over again, while Snowden has always told the truth, it's hard to believe them.
In this case, it seems very likely that people are going to get divorced, and that kids are going to go through the shredder over this.
Maybe you have to be middle aged to know this, but you hit a stage in life when people start having these incredibly hostile divorces, with really intense hatred on both sides. And that is terrible for kids. This is going to create that situation in lots of families. It's not cool. It's punching down, it's hurting people who had nothing to do with anything in order to get at some people who seem to be genuinely slimy (Avid Life).
