BTW I have my own story about this.

I actually have two Google accounts, my "real" one and the one I use to joke around on video game clips on YouTube. When Google strongarmed the second one into g+, I knew that even if I decided I wanted g+ for some reason, I would never, ever, ever want a g+ page on that YouTube account.

So imagine my surprise when I received an email beginning:

"This email was sent to you because you indicated that you'd like to receive Google+ Pages performance suggestions and updates"

Go to Hell, Google. I asked for no such thing, and if you somehow tricked me into accidentally not opting out of any such thing, you can still go to Hell. So if anyone says g+ tricked them into something, I'm going to believe them barring hard evidence to the contrary.
