1_ Google said it will follow a certain recognized standard, and it didn't follow that standard. If the standard were to be followed, then no "extra" track down of users would had happened.
2_ For those sites not following that standard (whether they declare it in their privacy policy or not), the user can be tracked down, and certain web browsers will not protect your privacy using their standard methods (while the user thinks it is enough to protect his privacy, but it isn't).
