Here's another one. Some of you may know that Diablo 3 (the game) was released yesterday. Now even in single player mode you have to "log in" to a central server for some sort of credential validation. I am guessing this is something to do with protecting the game from being pirated.
But guess what? The servers are down right now (possibly, overloaded). So even people who have paid good money, and are honestly sitting at home with their purchased product, cannot use it. There is something wrong here.
