In the course of this inquiry, we identified five key principles that we believe are crucial for regulation of social media and related technologies: 1) Public safety: Algorithmically accelerated misinformation is a danger that companies and government need to address—the government and platform companies should work together to protect the public from it. 2) Free and safe expression: Neither government nor private companies should be arbiters of truth. Steps to tackle amplified misinformation should be in line with the fundamental right of free expression, with restrictions where proportionate and necessary to protect national security, public safety, health, or to prevent disorder and crime. 3) Responsibility: Users should be held liable for what they post online, but the platforms they post on are also responsible, especially with regard to the systems used to moderate, circulate or amplify content. 4) Control: Users should have control over both their personal data and what they see online. This includes the right to delete the data stored by platforms and services which is used to drive content and advertisement recommendation algorithms. 5) Transparency: The technology used by platform companies, including social media algorithms, has huge public safety implications, and should be transparent and accessible to public authorities. (Conclusion, Paragraph 6) Misleading and harmful content on social media
