And does this distortion constitute a systemic risk under the Digital Services Act (DSA)? This blog article refers to our previous blogpost on "Platform Badges for Civic Communication", explains why such interventions are needed, and outlines how they could address these systemic risks.

How the Digital Services Act (DSA) Regulates Platforms

U.S. politicians accuse the European Union of endangering freedom of expression with the Digital Services Act (DSA). However, media law expert Dr. Christian Ollig argues that the DSA actually protects users' opinions from arbitrary censorship by platform operators. It also gives users a legal basis to assert their freedom of expression against large platform operators at the European level.

Communication Risks in Online Environments

How can German democracy remain resilient in the face of the communicative threats posed by the digital space?

The study found that climate scepticism and misinformation are common in social media debates. However, it is evident that these views are significantly less prevalent in wider society.
