> Tor is a solution for specific use cases. It does not address privacy on the internet in a general way. For example, if I use tor to browse facebook, I am logged into facebook and still just as trackable as I would be if I wasnt using tor.

No, at least now facebook may not know your exact location (especially if you use their onion service: https://www.facebookcorewwwi.onion/ ) and they can't track your activity outside of facebook. Of course, it doesn't solve - nor can any other anonymity system - the fact that you transmitted personally identifiable information with facebook.
