It’s been about two month since Facebook CEO Mark Zuckerberg answered (and sometimes evaded) questions about privacy, monopoly, and political discourse on the world’s largest social media platform. Now, in about 500 pages of documents, Facebook has answered more questions and elaborated on those not quite addressed at the hearings.
