With one simple change, Facebook could pass an important privacy test. Right now, users have little choice in the public exposure of their profile pictures. Every single one of them is set to “public” by default. Even if you try to limit your current profile picture visibility using Facebook’s privacy settings for the individual photo, it will still be public.
If you don’t want your profile picture to be public, the only winning move is to delete your account. That’s increasingly difficult to do these days, because not having a social media presence can limit your personal and professional opportunities and even raise the suspicion of authorities.
