A group of Apple Inc's critics — including Spotify Technology SA, Match Group Inc and Fortnite creator Epic Games — have joined a nonprofit group that plans to advocate for legal and regulatory action to challenge the iPhone maker's App Store practices.

Apple charges a commission of between 15 percent and 30 percent for applications that use its in-app payment system and sets out extensive rules for apps in its App Store, which is the only way Apple allows consumers to download native apps to devices such as the iPhone. Those practices have drawn criticism and formal legal complaints from some developers.

The Coalition for App Fairness, structured as a nonprofit based in Washington, D.C. and Brussels, said it plans to advocate legal changes that would force Apple to change. Beyond Epic, Match and Spotify, other members include smaller firms such as Basecamp, Blix, Blockchain.com, Deezer and Tile, along with developers from Europe including the European Publishers Council, News Media Europe and Protonmail.
