I've never understood this argument. Google Plus is free to do what they want, and we are free to say what we like about it. I have yet to hear a legal argument against Google Plus. What you call "unwritten law" is what other people call social norms. No one has said they cannot legally require real names, but that they should not require real names.
Leaving is not the only option when you don't like something.
Why would anyone start with siding with Google as their default position? Google Plus is not a finished product. When people complain about bugs or missing features for a new product they help to make a better product.
I agree that authors should avoid responding to reviews. However, this is the most gracious response to a review I have ever read from an author. From everything I have read from authors, it does not matter how many books they sell, bad reviews still hurt.
When I went to Columbia College, the GS students tended to be the best students. They were more prepared, more motivated, and had much more poise. If anything the GS degree would look better to me.
I know the snob factor goes down, but the GS degree should mean something to people who care more about education than branding or signaling.
