I'm a woman. I have a Facebook account and a journal. Both accounts are under pseudonyms and at least the Facebook account is listed as male. I won't use Google+. But I'll express myself all over the Internet. I have a right to say whatever I want without worrying about being stalked by some ass who feels the need to punish me for thinking without permission. My employer doesn't have a right to know anything about what I do off hours.
I retain, and will retain, the expectation of my right to privacy, even as I take advantage of my right to speak. The fact that an entity announces their intent to steal my private information, does not deprive me of the expectation of my rights. It just means that what I put where they can steal it will be of no value.
It's not like I can't have an online presence without Google+.
This article is RIGHT ON. Google+ IS screwing itself out of a large population of potential users , for these reasons, by these methods, and can take this valid feedback and... do what they do with feedback.
