The problem is that a lot of people were actively choosing not to use G+, but is now being forced to abandon other services, or face having separate identities merged. So for lot of people it is not as simple as "simply not using it" - if you had invested lots of time on YouTube for example.
Are talking about Google+ or the simulator?
I never seize to be amazed at how much energy people put into hating things when they could just simply not use it and then continue with their day.
