Anyone who signs up for Facebook and DOESN’T think that Facebook is sharing every single piece of data that it collects on you is very naive. If you are upset about Facebook, disconnect from Facebook. The model doesn’t work without selling your data.
Such "things" included people that can't spell, the SJW variant of keeping minute by minute updates of a walk/run for "charity", constant ads directed at you if you happened to mention something in a post, such as "washing machine", older relatives that suddenly discovered the hip farming game from seven years ago, etc.
