Facebook is an ad company. Credit card companies collect and sell purchase history. Giving them your cc number explicitly links your purchase history to your facebook account. Realistically they've probably already made the jump using your name and DOB, but at least they had to work for it...

Credit card companies sell data in aggregate. They don't sell your specific card history.

If you're paying for things through Facebook they don't need to contact your credit card company to get a list of payments they've facilitated, for obvious reasons.

Given that the best minds of this generation are working on making advertising more efficient, would it be surprising that such information would help Facebook?
