Is Facebook bad for democracy?

How the social media platform is poisoning politics around the world. A former Facebook employee says she has "blood on my hands" after struggling to contain the misinformation and manipulation conducted through the platform. Azerbaijani journalist Arzu Geybulla describes the coordinated Facebook campaigns against activists and politicians in her country. Berhan Taye, Africa policy manager at digital rights group Access Now, tells us why Facebook isn't doing enough to prevent the spread of hate speech in Ethiopia. And Siva Vaidhyanathen, author of a book 'Antisocial Media: How Facebook Disconnects Us and Undermines Democracy' explains why Facebook can't stop the spread of toxic content without undermining its business model.
