Google Expands Information Available through Topics API

Google continues to refine Topics API, its privacy-protecting ad targeting scheme for the post-third-party-cookie world.  The latest changes add some 280 commercially-focused categories, let advertisers learn a little more about the topics a person has consumed, improve speed, and let people block selected topics in advance.  You’ll note the trend here is to give more information to advertisers, which is another way of saying less privacy to everyone else.
