Key Points:

- Industry groups IFPI and NMPA support YouTube's position
Financial Impact:
- Musi generates millions in monthly ad revenue
- The app earned over $100 million in advertising revenue between January 2023 and Spring 2024
- Apple contends Musi isn't at financial risk since existing users can still access the app
- The company reportedly employs 10 or fewer people
Current Status:
- Musi remains unavailable for new downloads on the App Store
- Existing users are seeking alternatives like Apple Music and YouTube Music
- Musi has not yet responded to Apple's latest filing
- The app continues to operate for users who previously downloaded it
The case highlights ongoing tensions between app developers and platform providers regarding content usage, advertising practices, and compliance with terms of service.
