Even worse, if they decided they didn't believe you were you, the account would be terminated. And because it was all tied together, it would take youtube, gmail, and your android phone with it. I don't care too much about most of that, but I actually use my phone for real world stuff. I wasn't about to risk getting my address book and apps screwed up just for a google+ account that I might or might not ever post to. That and I'm obe of those people who feels no need to announce my visits to the toilet to 6 billion+ people. I really don't want all of my logins on everything tied together into a bit glueball.
Couple that with Google's policy of never ever letting you talk to a human being no matter what your question or concern might be and there you go, no google+ for me.
Relaxing their policy meant one of two things, they realized they made a mistake, or google+ had lost internal support and would be pining for the fjords any time now.
