It's edited, sorry! I felt it was important to clarify that the general Privacy Sandbox concept they are promoting is designed and built around allowing data collection about users that can be used for ad targeting, whether it utilizes third party cookies explicitly or not.
Note that blocking all cookies breaks the web, blocking third party cookies breaks adtech. It's important to note that even if Chrome has supported the former, it has resisted implementing the latter.
Meanwhile, Firefox, Edge, and Safari have chosen to implement tracking prevention, which has the goal of preventing any ad targeting towards a given user.
