Some degree of analytics to determine how users are interacting with your online property, I understand. And, I understand that many want to source those analytics to a third party (e.g. Google Analytics). However, the third party tracking that enables advertisers to notice a view or interest and then "haunt" users across multiple sites for days with ads related to that view? That aggregate and warehouse such knowledge, building up extensive profiles that become their own form of property and that may be used and sold against the target user's own best interest? (So, you're looking at information related to diabetes? I bet health insurers would be interested in that...) I have very little sympathy for those use cases.
