You can see all the domains they add the header to here: https://news.ycombinator.com/item?id=21034849

Actual list: https://cs.chromium.org/chromium/src/components/google/core/...

  • This seems like a cut-and-dry case of getting caught in monopolistic behavior. The code is right there. The Chrome codebase has special features for Google’s own web properties.

    I hope all these AGs suing google have some good tech advisors. It’s hard to keep track of all the nefarious things google has been up to over the past decade.

      ???

      Is "Darn, their browser only gets to track me on their own websites; if Google were playing fairly, they'd send the tracking header to all websites so I can be tracked more and have less privacy" the argument you're making here?

      And it's debatable that this header is actually serving a tracking purpose at all. Being limited to their own web properties cements it as a diagnostic to me. What use is a tracking header that only gets sent to domains they already know you're visiting?

  • Security flaw? Surely some entity is squatting youtube on some TLD?!

    If there is a country TLD of X where Google owns google.X but entity Y owns youtube.X then entity Y gets the X-CLIENT-DATA header information. See usage of IsValidHostName() in code.
