Device: Any desktop app, all platforms.
I can see "Friend activity" even Spotify is NOT connected to Facebook. Screenshot attached as proof. This happens on both Linux and Mac, I assume people who used to be my Facebook friends also see whenever I'm online in Spotify and what I am playing.
I _do not_ have Facebook anymore, or had for years, but there seems to be no way to fully disconnect FB even FB account itself is gone. *Also this account is NOT registered through Facebook*, but sometime in the past I did connect to it.
No option in the UI or web settings affects this, I can still see people in friends feed, and probably they can also spy me, including people I don't want to even know I'm alive.
What to do?
