European Union watchdogs fined Apple and Meta hundreds of millions of euros Wednesday as they stepped up enforcement of the 27-nation bloc’s digital competition rules. The European Commission imposed a 500 million euro ($571 million) fine on Apple for preventing app makers from pointing users to cheaper options outside its App Store.

The sanctions mark the first from EU antitrust regulators under new sanctions brought in to curtail the dominance of Big Tech

The EU has fined Apple €500 million, or $565 million, over the App Store’s terms of service. The company was found to have breached a section of the DMA that focuses on how mobile developers sell in-app items.
