I have never seen a more foolish comparison than the TV one. If someone doesn't watch TV, at best the in crowd might think you are a fool and behind the times.
The shadow profiles maintained by Facebook is the equivalent of watching your TV by stealing the non-watcher's electricity.
Triangulation of other people's profiles based on your phone book is the equivalent of handing over your non-watching neighbor's address to the (physical mail) spammers and then going and collecting only the interesting stuff from their house by using their key without their knowledge or permission.
Calling someone a spoil sport for pointing out the problems that FB causes to non-users is the equivalent of turning up the volume on your TV to a 1000 and telling your non-watching neighbor that all they need to do to drown out the noise is to go get a TV and then do the same.
