I'm losing track of all the tracking injections, but Debbie says that G is building an Apple-like walled garden of new, assorted tracking methods that -when assembled in their boiler room- replaces cookies in the literal sense.
This will be a Google-wide initiative and not just Chrome. For instance, Ublock just flagged/blocked a raft of new scripts and google-owned domains being added to G News --mostly affecting the "local" section.
