The tobacco industry might once have funded a study that says that smoking is less dangerous than coal mining, but here we have a study about coal miners smoking. Probably while they are in the coal mine. What I mean to say is that there is no scenario in which "user choices" vs. "the algorithm" can be traded off, because they happen together.
Facebook probably just needs to stop publishing research on their data if they're going to continue to do it incorrectly.
