If you care, stop using Chrome. If you criticize this evil move, but continue using Chrome, you are part of the problem.
Not using Chrome comes with zero cost - you can use the same websites everyone else is using, just use Firefox.
Your social graph is more accessible to other 'actors' than it would be if it weren't on Meta.
You may not care about this kind of thing, but I do. Unfortunately I'm not entirely free of it either, so any finger wagging on my part is at least partially hypocritical.
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!
Not quite. Increasingly, as Chrome became popular, you get websites that "work better in Chrome". Or do not work at all in other browsers. And you hear recommendations to "just use Chrome", so that things work. It's just more convenient all around.
