Part of the problem is that Google -had- a policy of being very supportive of people choosing whatever name they wanted. This goes against all their former statements. (They are also enforcing the current G+ name policy very, very inconsistently.)

Another problem is that many people do not want an Internet where "name that can easily be linked to your job, your address, and all your family and friends" becomes the status quo, and if one of the biggest names in the Internet makes "real" name required, it will be easier for more companies/services to do the same later on.
