This is interesting. I always new the big tech companies had trackers all over the place, but I didn't realize it was so bad.

Would be interesting to run this with and without ad blockers and other filter lists to see how good they do at actually protecting you from tracking.

Presumably it's google analytics. Some ad blockers will block google analytics. Also Google Analytics claims to not do cross site tracking or build user profiles, whether you believe that is up to you, but it's incredibly commonly used by website owners to track their own traffic.

This kind of setup could reveal which blockers are best at keeping data
