Sure, but that's not the same thing: people overwhelmingly choosing to opt out when presented with a binary yes/no prompt is not the same thing as caring as much as you about privacy. Those people aren't going to start campaigning for privacy regulation because they opted out of Facebook's additional tracking. I generally refer to this as the "Don't Send" principle, if you remember those old Windows errors.
