Too much power in a few hands is inherently dangerous. That goes for private as well as public, or governmental, power. In the world of social media, the companies that own and control the platforms are essentially governmental in nature in that the executives promulgate rules and, ideally, see that they are enforced. The downsides to too few platforms—each with an extraordinary amount of power—involve a constricting of ideas, or content, on the internet, and potentially unanswered violations of the rights of the social-networks’ respective users. The public policy repercussions, I submit, include applying anti-trust law to social media companies such that none gets to become as massively dominating as Facebook had been allowed to become.
