I mean, at one time you could build apps on Facebook that basically downloaded all of a user's data when they used it. The Obama campaign built an app that you could use to find your Facebook friends who hadn't been contacted by the campaign yet, so you could call them on the campaign's behalf. I heard of other political operations that built a "wish [famous person] happy birthday" app solely so they could grow their database.
Eventually Facebook closed all that access down and basically deprecated the concept of FB as an app platform entirely. That is a way more dramatic change than what Apple is doing to Facebook here.
