The Advocate General’s opinion interprets Article 5(1)(c) GDPR to require Meta to restrict the use of personal data for targeted advertising by time, type and source. It also addresses purpose‑limitation, stating that publicly disclosed information cannot be used for unrelated advertising purposes. The opinion follows questions referred by the Austrian Supreme Court to the CJEU.
Why it matters: The opinion could force Meta and similar platforms to delete or limit historic user data used for advertising, reshaping EU online ad practices.
