alt Hacker NewsThis is very misleading. Google was prevented from disabling third-party cookies due to intervention by the CMA, who felt it would provide an unfair advantage over other advertisers. Google argued their case for years, proposed competing standards to act as a replacement (see Topics API), and eventually gave up on the endeavour altogether and simply made it a user toggle.
Google gets no competitive advantage from removing third party cookies from chrome. The anticompetitive monopolistic tactic was the plan to replace third party cookies with FLoC/Privacy Sandbox/Topics AI, and THAT is what they were not prevented from doing.
No one is trying to stop google from removing third party cookies. Google is just unwilling to remove them without introducing a new anticompetitive tracking tool to replace them.
