In this competitive environment, it is hard to sustain the claim that Facebook is a monopoly. Almost all of our revenue comes from digital advertising, and most estimates say Facebook’s share is about 20 percent of the United States online ad market, which means 80 percent of all digital ads happen off our platforms.
The second misunderstanding is of antitrust law. These laws, developed in the 1800s, are not meant to punish a company because people disagree with its management. Their main purpose is to protect consumers by ensuring they have access to low-cost, high-quality products and services. And especially in the case of technology, rapid innovation. That is exactly where Facebook puts its attention: building the best products, free for consumers, and funded by advertisers.
What antitrust law isn’t about is size alone. In Facebook’s case, our size has not only brought innovation, it has also allowed us to make a huge investment in protecting the safety and security of our services.
Over the past two years we’ve focused heavily on blocking foreign adversaries from trying to influence democratic elections by using our platforms.
