Forced to log in?

When I first saw that I was being forced to log in just to access this website I thought it must be some kind of phishing hack and Blizzard would fix it. But days later and the same thing. Why would Blizzard do this? To show the board members all the people creating new accounts (because they need to create one if they don't have one to access the site?)

Anyhoo, my main reason for this post is to ask the question - is it really Blizzard doing this? Or do I actually have malware on my computer and I just got phished?
