Interesting. He really puts Facebook into the role of policing its users (and advertisers). He describes taking down thousands of fake accounts, investigating whether certain pages have connections with IRA and taking them down if so. This will probably sound reassuring to legislators, but it pretty much permanently accepts the burden of responsibility for misinformation on the site. It sounds likely to force Facebook into a costly permanent arms race against every malicious political actor in the world. I wonder how regular users will get caught in the crossfire. Not that I feel bad for FB here -- they make tons of money because they have the most captive attention of any entity in the world. Attention is valuable because it allows platforms to influence people's behavior toward certain actions. Advertisers are not the only ones who realize this, and FB has to take responsibility for all forms of influence on its site, not just commercial ads.
