I wasn't making any argument here about what anyone should or shouldn't do. I was simply pointing out that it's not the case that deleting your FB account gets you "out of the game" when it comes to being tracked. That's not the same thing as "it doesn't make any difference".
FWIW, I have a FB account, never initiate friend requests, log in rarely, post ~never. I make no claim that this is the "best" strategy by any particular metric.
