The Court of Justice of the European Union (CJEU) ruled on October 4, 2024, that Meta must limit its use of personal data for targeted ads. The decision enforces GDPR’s data minimization principle, restricting Meta’s data collection, even with user consent. Sensitive information, like sexual orientation, cannot be used without explicit permission. This ruling forces Meta and other ad platforms to tighten data handling practices, with national courts set to oversee compliance.
