The Higher Regional Court (OLG) of Cologne, Germany ruled regarding the permissibility of using personal data for training artificial intelligence (AI). The core issues included data protection concerns of Meta’s practices and whether the planned use of publicly accessible data from European users on Facebook and Instagram for AI training purposes violates Article 5(2)(b) of the Digital Markets Act. The decision provides an initial important orientation for platform operators and gatekeepers in dealing with personal data for AI training purposes.
