Yes. By befriending someone on Facebook you gave them access to data you chose to share with your Facebook friends. You don't get to choose what they do with that data. It's just like if you tell someone something irl and they use that info in a way you don't like. Once you share info you can't put the genie back in the bottle. Unfortunately, Facebook has a history of changing data permissions that have caused info to be shared in ways users didn't intend.
