The way content is governed by dominant online platforms that have become gatekeepers to information is not only relevant for the realization of freedom of expression and media freedom but, ultimately, for international peace and security. Content governance determines the availability of information, the accessibility of public interest content, and the administration of information, including across borders. As online platforms deploy artificial intelligence (AI) to support the curation and dissemination of content as well as to filter and take down unwanted content, AI-led processes provide the basis for how security interacts with information online today. The emergence of technologies like generative AI raises additional questions concerning content production and the broader effects on the way information is distributed and perceived.
