Making a public profile does not mean revealing all the services in which you have registered. Putting the Flickr, Twitter, Facebook, blogger or Picasa account of each user will still be optional, but it will be mandatory to reveal, at least, the username.
In a message within Google's help section, the decision is explained and exposed: "The goal of Google profiles is that you can control your online identity. Today, almost all Google profiles are public. We believe that the best use of these profiles is precisely to help them find you and contact you online. Private profiles do not offer this possibility, so we have decided that all profiles are public.
Please note that the only mandatory data that will be displayed in the profile is the full name. You can modify or delete any other information you don't want to share.
If you currently have a private profile and don't want to make it public, you can delete it. Or, just don't do anything. All private profiles will be deleted as of July 31, 2011."
This measure will cause those who have inactive accounts to lose them, but also that those who use them to comment with the intention of generating noise or disturbing in different services lose their accounts. It is not a final impediment, but it will be more annoying to create anonymous accounts.
