I remember being Google very proud about the fact that they don't need your real name in order to track you with ads, a few years ago. But somewhere along the way, Google caught a lot of Facebook envy, also influenced hard by the media who kept saying Google will die if it doesn't create its own social network, and once Facebook creates its own search engine, it's game over for Google. Of course that was silly, because Google's search engine doesn't work just through social media signals, which is why Facebook's search engine could never have been as good as Google.

But anyway, the point is they caught this Facebook envy, and they wanted the real name policy, too.
