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.
