As part of the settlement, Google is barred from "misrepresenting the privacy or confidentiality of individuals' information or misrepresenting compliance with the U.S.-E.U Safe Harbor or other privacy, security, or compliance programs." It also requires Google to affirmatively obtain consent [opt in] "before sharing their information with third parties if Google changes its products or services in a way that results in information sharing that is contrary to any privacy promises made when the user's information was collected."

I thought it was rather interesting that they agreed to 20 years of audits.

After spending over 100 man hours compiling evidence for the EU courts I'm guessing Google is starting to feel sorry for MSFT after the last 10 years they were the dominating/monopolistic big boy of the Internet.
