Cypriot lawyer Petros Papadopoulos has filed a lawsuit against Meta Platforms Ireland Limited, challenging its ban on political advertising and the operation of its content algorithms. The case, brought before the Limassol District Court, argues that Meta's policies and algorithmic controls significantly restrict political expression and communication on Facebook and Instagram, which are vital channels for public discourse.

Papadopoulos contends that Meta's ban on political and electoral ads within the EU, together with reduced organic reach and opaque ranking criteria, limits his ability and that of other politically active individuals to reach audiences effectively. The lawsuit highlights concerns about transparency, alleging that insufficient information about how content is ranked creates an imbalance that hinders verification of reduced content visibility.

The case raises broader questions about the role of large tech companies in democratic processes, asserting that Meta's platforms have become essential infrastructure for political communication. Papadopoulos stated that social media giants should be held to the highest standards for protecting freedom of expression and ensuring meaningful participation in public debate. The lawsuit remains at an early stage, with service to Meta pending due to cross-border complexities.
