I care, and my feeling is that more people do each day as they become aware of how tracked they are. Why does anyone need to know anything about me - it feels like a violation. There are all sorts of possible costs to that, but I think many of us value privacy on its own.
But as for an attacker - maybe they discover something about you from one compromised service and correlate it to something else. Or maybe they extort you in some way. Who knows - there are many possibilities and it’s safer to reduce exposure.
