As far as I can tell, that is untrue. CMA has explicitly stated concerns with any removal of third party cookies by default from Chrome, since they believe ad tech companies are dependent on them but Google isn't. Any new mechanisms introduced for privacy preserving ad targeting are irrelevant, except insofar that they could be used to satisfy the needs of said ad tech companies. That other browsers have been allowed to remove third party cookies by default is also irrelevant: the fact is still that Chrome is not being allowed to do so.

Oh, come on.
