If anything it sounds like "related" is not what they are actually doing. Rather they are looking at ways to uniquely fingerprint users through optimizing how they split "related" sites.

Reminds me of the research that shows that 87% of people in the US can be uniquely identified with only three pieces of information: date of birth, gender, and zip code [1].

Chrome backtracked on the decision, they won't be blocking third-party cookies. There were a number of articles and a fair bit of discussion about it at the time, see e.g. [0] and [1].

It's complicated. Chrome won't block 3rd party cookies by default . But it will present the users with a choice of whether to block them (with what exactly that means TBD). If most or all users choose to block them then it would have roughly the same effect as blocking third party cookies by default would. Though regardless of that, Related web sites (or whatever that set is currently called) does present a hole in t…

Sure but most won’t unless the “go away now” button is “block” which I’m guessing Google wouldn’t do.

Google wanted to (that's why they created stuff like FLoC) but other advertisers didn't like that and went to the market authority. They demanded the ability to track users, arguing that the system would give Google an unfair advantage.

After years of back and forth, Google abandoned their efforts. You can still disable third party cookies, in fact I don't think there's been a version of Chrome that doesn't let you block them. Go to your settings and set "third part cookies" to always be blocked. By default, grouped sites may be permitted to read each other's cookies, but you can disable that too.

The problem Google faces is changing the default, simply blocking third party cookie has never been an issue.

That seems to be saying it is extremely likely that the only other person in my zip code that shares my birthdate is opposite gender
