The U.K.'s Competition and Markets Authority said it's investigating Apple over "complaints that its terms and conditions for app developers are unfair and anti-competitive."
It said that the investigation "will consider whether Apple has a dominant position in connection with the distribution of apps on Apple devices in the U.K. — and, if so, whether Apple imposes unfair or anti-competitive terms on developers using the App Store, ultimately resulting in users having less choice or paying higher prices for apps."
