Doesn't really understand what people are upset about. In the big picture, yes, it's a problem. Some people could start receiving better and more believable phishing emails and the uneducated could fall victim to a scam. However, for an individual who practices safe email habits, this is not a big deal. It might increase spam. I can deal with that.
It's not like these companies aren't trying everything they can to protect the information; hackers are just that good. I see it like a giant game of whack-a-mole--eventually every company is going to lose.
