Meta said it would appeal the decision by the European Union, which said the company had abused its dominance in social networking to strengthen its shopping and classified ads service.

An EU commission alleged that Meta leveraged its dominance in social networking to gain an unfair advantage in online classified ads.

The European Commission, the executive arm of the European Union, has hit Meta, the company that owns Facebook, Instagram, and Threads, with a fine worth $840 million for what it classifies as an antitrust violation.
