GA surely delivers that data to google, and tries to correlate through a GA specific domain.
Now, they might not provide it to the site owner unless they opt in (to also share it with DoubleClick or whatnot), and they might pinky swear not to use it (though I have never seen that promise myself).
But using GA, a site makes your naive browser send all that data to google. Why would you assume it is not being used? Does it matter if for now it is only directly visible to google?
