CNBC:

The antitrust theory against Apple centers on its control of the App Store. A potential case against Apple could look similar to one against Amazon, focusing on the fact that it both owns a marketplace (the App Store) and has its own pre-loaded apps such as Apple Music and Apple Podcasts that compete with other apps on its platform, such as Spotify.

Some developers who offer their apps through the App Store — the only way Apple allows for apps to be added to users’ devices — have complained about Apple’s opaque and sometimes seemingly arbitrary process for accepting new apps.

The documents released paint a picture that Apple’s rules around its App Store may not be as rigid as the company has repeatedly insisted they are.

There’s nothing damning here against Apple.
