EU regulation has led to Apple being forced to open up iOS in ways that many never expected, but it’s not done just yet. In an effort to ensure “effective interoperability” with other platforms, the EU wants Apple to make native features of iOS being compatible with Android, including the likes of AirDrop and more.
When something is subject to the network effect, competition requires interoperability. This applies almost universally to technical standards.
