Twitter has much in common with other prominent “Big Tech” social media firms such as Facebook and Google-owned YouTube. Like these firms, Twitter is centralized, with one set of rules and policies. Twitter is nonetheless different from other social media sites in important ways. Although often discussed in the context of “Big Tech” debates, Twitter is much smaller than Facebook and YouTube. Only about a fifth of Americans use Twitter and most are not active on the platform, with 10 percent of users being responsible for 80 percent of tweets. Despite its relatively small size, Twitter is often discussed by lawmakers because of its outsized influence among cultural and political elites.
Republican lawmakers’ focus on Twitter arose out of concerns over its content moderation policies. Over the last few years it has become common for members of Congress to decry the content moderation decisions of “Big Tech” companies. Twitter is often lumped together with Facebook and YouTube in such conversations, which is a shame given Dorsey’s views on free speech.
