Why does the google safety center say to never use your real name online, but google+ demands you do?

Is it just me, or does something not smell right with google+?

- Googles official safety policy is to never share personal details or real names, Yet google+ demand a real name is used.

- Google employees have been spotted using Google+ with fake names such as “Talon”.

- Some businesses are shown favoritism, while others are simply banned from the site.

The list of issues goes on.
