> This makes no sense. Nothing happens "automatically", someone wrote the code for that to happen, in this case, Facebook.

The website you are visiting has to deploy Facebook's code though. So the website owner has to allow it (assuming the know the implications of what they are doing).

You could assume it but it's not necessary the same people who designed the web page that add those facebok "features". From my impression, often than not you have some "social media marketing expert" that does this. And they do not give a rats ass about any nefarious tracking and will continue to be blissfully ignorant about the users privacy unless it becomes a corporate policy to care about those things.

The website owner still has the ultimate responsibility for what is served on their site.

If they employ some "social media marketing expert" who deploys tracking code, then that's still on them.

On the other hand, Facebook could design their social media widgets in a way that doesn't require the user to send a GET request to Facebook unless the user actively clicks to share.

Also know as a link. That's not Web 3.0 enough.

Most of these sites don't want you to navigate away from their page. They would rather you can share without leaving their site (i.e. a dialog pops up that allows you to create your Facebook "share" post, and submit it).
