Installing Google Analytics on a website allows Google to track users visiting the site. Can Google not follow this same user across different GA-enabled sites (e.g. through a cookie)? And can Google not connect this user with search terms entered on its website? If that is the case, that seems to be a significant amount of data that would potentially fall foul of European privacy laws.
The commenters on Techcrunch, however, seem to think the issue is with the users of Google Analytics (the web site operators) gaining private data. It isn't. It's with Google getting this data.
