That makes it right?
At some point, most of us are "home users" so it is important. And most of us don't have a KMS (Key Management Server) at home. Why should we have to suffer with such lunacy? I will stick with Office 2010 (which I have several keys for) for now. I have no compelling need to upgrade as I barely use any of the more advanced features anyway. If I ever need to upgrade, I'll look at the alternatives as I have no desire to get involved with their rental program.
