1. Mandatory Support for Third-Party App Stores

A cornerstone of the new legislation is the requirement for dominant mobile operating systems to support third-party app stores. This mandate compels companies like Apple and Google to allow alternative marketplaces on their platforms, breaking the exclusive control they previously held over app distribution.​

By opening up the ecosystem, the law aims to:​

• Enhance Consumer Choice: Users gain access to a broader range of apps and services, potentially at more competitive prices.​
  
  
  
• Promote Developer Autonomy: Developers can distribute their applications without adhering to the stringent policies and fees imposed by the primary app stores.​
  
  
  
• Stimulate Innovation: A more diverse marketplace encourages innovation by reducing barriers to entry for smaller developers.​
  
  
  

This move aligns with global trends, as regulators worldwide scrutinize the dominance of major tech companies in app distribution.​

2. Prohibition of Preferential Treatment for Proprietary Apps

The second rule targets the preferential treatment that platform owners often give to their own applications. Under the new law, companies are prohibited from favoring their proprietary apps over those of third-party developers in areas such as:​

• Search Rankings: Ensuring that search results within app stores are unbiased and based on relevance rather than ownership.​
  
  
  
• Pre-installation: Preventing the automatic installation of proprietary apps on devices, giving users the freedom to choose their preferred applications.​
  
  
  
• Access to APIs and Features: Guaranteeing that third-party apps have equal access to operating system features and application programming interfaces (APIs).​
  
  
  

By enforcing neutrality, the law seeks to create a level playing field where all developers have an equal opportunity to reach consumers.​

3. Transparency in App Store Operations

Transparency is a critical component of the new legislation. The law mandates that app store operators disclose clear and comprehensive information regarding:​

• Fee Structures: Providing detailed breakdowns of any fees charged to developers, including commissions and transaction fees.​
  
  
  
• Review Processes: Outlining the criteria and procedures for app approval, ensuring that developers understand the requirements and reasons for any rejections.​
  
  
  
• Policy Changes: Communicating any modifications to app store policies in a timely and transparent manner.​
  
  
  

This rule aims to build trust between app store operators and developers, reducing instances of arbitrary decision-making and fostering a more predictable business environment.​

Implications for the Tech Industry

The enactment of these rules is poised to have far-reaching effects on the tech indu
