That's beside the point, though. The point here is that Facebook executives were told by their own employees that the algorithms they designed were recommending more and more partisan content and de-prioritizing less partisan content because it wasn't as engaging. They were also told that this was potentially causing social issues. In response, Kaplan/FB executives said that changing the algorithm would be too paternalistic (ignoring, apparently, that an algorithm that silently filters without user knowledge or consent is already fundamentally "paternalistic"). Given that Facebook's objective is to "bring the world closer together", choosing to support an algorithm that drives engagement that actually causes division seems a betrayal of its stated goals.
