The vast majority of Googlers do not approve of G+ policies. However, Google has never been run democratically and most of the time that's probably a good thing.
Furthermore, the management has been much less forthcoming than usual about the thinking behind these policies. What they have said varies and usually sounds like excuses.
In short, don't expect actual information in this thread.
For me, this is the most critical statement in the entire Google+ saga. Most Google employees do not approve of a strategy that google is betting its future on. Has this ever happened before? Probably never before. And to me, it marks a clear beginning of the end of google as we knew it. The google we grew up loving was a google that put product quality before anything else. Everything else(such as market share) was a result of a good product. This is no longer true.
It was before my time, but I'm told acquiring youtube was unpopular. That seems to have worked out. I doubt it was as unpopular, though, and there was a lot less bet on it.
Much as it pains me to admit that I'm not omniscient, there are ample examples of products where the majority Googler consensus does not reflect the majority market consensus. There are also ample examples of products where the initial market consensus doesn't reflect the final market consensus. (For example, Chrome was beloved internally by Googlers, but was met with a lot of external skepticism when it launched, and then eventually became the dominant browser.)
