Filed in the US District Court in the Northern District of California, the suit is led by Utah, North Carolina, Tennessee, New York, Arizona, Colorado, Iowa and Nebraska, Politico reports. The suit comes as regulators and developers around the globe question the way Google and Apple wield their power over the marketplace for mobile applications. Last September, Google gave all Android developers a year to adopt its in-app billing system for apps distributed on the Google Play Store to sell digital goods. The move was designed to stop some popular apps, such as Netflix, Spotify and Epic Games, bypassing the system – and the 30% cut Google took from those transactions. Epic sued both Google and Apple over their respective app store policies. Subsequently, both Google and Apple halved their standard commission on in-app purchases. Data from the second quarter of 2021 shows that the app market is booming. Users spent a record $34 billion in the quarter, with iOS App Store users spending $22 billion and Google Play store users spending $12 billion.
