Facebook is making money off the fact I still visit their website enough to show me sponsored content (much like most of the rest of the internet does), and the data in theory means purchasers of its ads get better bang for their buck. I'm not convinced the fact that I'm a 30something single male currently located in a particular area is something anyone would pay me for, and granting Facebook right to use those facts plus data from ad-retargeting networks to show me ads and sponsored content (some of which I haven't even managed to block!) for free use of their web platform seems like a pretty fair trade to me.

tbh I'm not even convinced half the data is actually that good for the ad platforms: the fact that I invariably report obvious ICO scam ads as "it's a scam" seems to have triggered Facebook to show more of them to me.
