A group of Apple's critics - including Spotify, Match Group 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 15%-30% for apps that use its in-app payment system and sets out extensive rules that apps must comply with to appear in its App Store, which is the only way Apple allows consumers to download native apps onto 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 DC 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.
Sarah Maxwell, a representative for the group who previously worked at financial technology firm Blockchain.com and Hillary Clinton's campaign, said the group was founded out of "a lack of hope that things will ever change" and aims to recruit more developers.
"While it's great that we have the big names like Epic and Spotify in the group, we're not speaking just for them," she said in a interview.
Epic is suing Apple over antitrust claims in a US federal court in California, while Spotify has filed an antitrust complaint against Apple in the European Union. Ms Maxwell declined to comment on how much funding the Coalition for App Fairness has raised and from whom.
The group also laid out 10 'App Store Principles' it plans to demand, including that "No developer should be required to pay unfair, unreasonable or discriminatory fees or revenue shares."
