It does not compromise the user's privacy in any way. GA prohibits PII. Also, the webmaster has to opt-in to share the data with Google in the first place.

If you don't get to automatically participate in a "anonymous" usage survey, have you lost something you can not undo?
That in my opinion, is why software should always err on the side of privacy.
...anyway, complaining about getting downvoted is a surefire way to keep getting downvoted :P
