How is it Blizzards fault that the people getting hacked have not managed to secure THEIR OWN machines and have had their username and password stolen ON THEIR END!
I currently do not have an authenticator, I have never been hacked, am I mad that I am now required to pay 6.50 so that my account is more secure if I chose to involve real money, ABSOLUTELY NOT!
Its called a brain, use it!
You said so yourself...if you "chose to involve real money". Then don't.
