Already now I have to rename my stats script from 'track' to 'res', otherwise I only see about a quarter of users. (I'm just using it to count how many views each page has, not for tracking.)
The endgame is to move all ad and tracking code to 'first-party', i.e. the website delivers the code in its source. (Un?)fortunately that is not happening quickly since advertizers distrust the publishers.
