If you care, stop using Chrome. If you criticize this evil move, but continue using Chrome, you are part of the problem.
Let's say I have a kid at a school. I don't use WhatsApp, but several parents have me in their phonebooks. They use WhatsApp and also use Facebook on their phones. Facebook gathers their location information, and given what Facebook knows about them, it isn't difficult to infer that I also must have a kid attending a school at a particular address at particular times during the day.
Data mining quickly gets scary.
You can also look at it another way: if this information wasn't valuable, do you think Facebook/Meta would have paid a billion for WhatsApp back in the day? Do you think they maintain the "end-to-end encrypted" communications app out of the goodness of their hearts? This is extremely valuable information: millions of people share their identifying information (their phone number) and their social network (their phonebook). It's worth a lot!
