1. Apple's App Store has faced increasing scrutiny over its 30% commission on in-app purchases, with developers and regulators arguing that it stifles competition. The European Union has accused Apple of distorting competition in the music streaming market through its App Store rules, and the company is facing a similar lawsuit in the US.

2. In response, Apple has proposed allowing developers to use outside payment systems for in-app purchases, a move that could significantly reduce its commission revenue. However, the company is also seeking to maintain control over the App Store ecosystem, proposing that developers who use outside payment systems would still need to provide information to Apple about their transactions.

3. The article notes that Apple's proposed changes are part of a broader effort to address antitrust concerns and avoid further legal battles. The company is facing increasing pressure from regulators and developers to loosen its grip on the App Store and provide more opportunities for competition, which could have significant implications for its lucrative commission-based revenue model.
