As hard as it is to curb election propaganda, Zuckerberg’s most intractable problem may lie elsewhere—in the struggle over which opinions can appear on Facebook, which cannot, and who gets to decide. As an engineer, Zuckerberg never wanted to wade into the realm of content. Initially, Facebook tried blocking certain kinds of material, such as posts featuring nudity, but it was forced to create long lists of exceptions, including images of breast-feeding, “acts of protest,” and works of art. Once Facebook became a venue for political debate, the problem exploded. In April, in a call with investment analysts, Zuckerberg said glumly that it was proving “easier to build an A.I. system to detect a nipple than what is hate speech.”
