Facebook doesn’t care about the Like buttons you don’t click. They care about receiving an HTTP GET request at their server for every web page you view so that they can collect the IP address (and potentially the Facebook cookie info) so that they can build a profile of each user’s browsing habits and resell that data to industry or build products around it.
“If it hadn’t occurred to you yet that Facebook cares far more about the “Like” buttons that you don’t click than about the ones that you do — there you go.”
