Apple is being sued by developers who claim it uses its "abusive monopoly" power to force them to pay a high commission rate for sales of apps through the App Store.

The lawsuit, filed Tuesday, comes as Apple and other big tech companies like Google and Facebook face mounting antitrust scrutiny, including a potential probe from the U.S. Department of Justice, according to Reuters.
