It's quite funny that a company like Google has both a web security team in charge of squashing fingerprinting methods, and an analytics team in charge of exploiting those very methods to the fullest extent.
Then again it kind of makes sense. Who better knows?
Well, I think it honestly harkens back to Google's original "Don't be evil" motto. I think most of the people at Google want to "Do the right thing" as long as they keep their jobs.
They want to find the right balance, the problem is I think a large portion of Google has lost their way in that regard due to the need to make Google more money. If the volume isn't growing fast enough, they have to find newer...higher margin...options to grow.
I would imagine this has value not just to analytics. Deanonymization has a lot of value in curbing abuse. Privacy is of paramount value, though, so it's hard to reconcile. To me it's a dilemma.
