Google settled its case with the FTC over the forced joining to Buzz for a brief period after its launch last year, they now have to have users sign up for the product.
Google will also face bi annual privacy audits by the FTC. That should prove overwhelming should Plus! become as popular as the Facebook Like button.
The settlement can be found at the government's site.
"When companies make privacy pledges, they need to honor them," said Jon Leibowitz, Chairman of the FTC. "This is a tough settlement that ensures that Google will honor its commitments to consumers and build strong privacy protections into all of its operations."
Google responded on their blog "we don't always get everything right. The launch of Google Buzz fell short of our usual standards for transparency and user control--letting our users and Google down. While we worked quickly to make improvements, regulators--including the U.S. Federal Trade Commission--unsurprisingly wanted more detail about what went wrong and how we could prevent it from happening again. Today, we've reached an agreement with the FTC to address their concerns. We'll receive an independent review of our privacy procedures once every two years, and we'll ask users to give us affirmative consent before we change how we share their personal information.".
They do realize their new Plus1 ties in to Buzz and thus will be under audit for 20 years.
