Get your FOMO on!
In the open air, fake news can be debated and exposed; on Facebook, if you aren’t a member of the community being served the lies, you’re quite likely never to know that they are in circulation. It’s crucial to this that Facebook has no financial interest in telling the truth. No company better exemplifies the internet-age dictum that if the product is free, you are the product. Facebook’s customers aren’t the people who are on the site: its customers are the advertisers who use its network and who relish its ability to direct ads to receptive audiences. Why would Facebook care if the news streaming over the site is fake? Its interest is in the targeting, not in the content.
