> Even if you are not using Facebook, even if none of your friends ever use Facebok or tag you in any content, Facebook is maintaining a shadow profile on you.

That's a more general flaw with the current web. Just look at how much 3rd party content is embedded into almost any site. A good chunk of them are user trackers. Facebook is just one among many.

I think we need stronger compartmentalization in the web. The iframe sandboxing + message-channel APIs is a good start to isolate things and minimize information leakage, sadly that doesn't help with libraries loaded from CDNs. Mozilla's contextual identities is another approach[1]
