It wasn’t all that surprising to see Apple Music launch on Android, despite Apple’s aversion to releasing its software on other platforms, because there’s no way the music-streaming service would be able to succeed without tapping into the massive Android userbase. However, CEO Tim Cook recently revealed to some of Apple’s employees that the company didn’t just release Apple Music on Android out of necessity, it did it to test the waters to see how interested Android users would be in using Apple apps. Bringing its apps and services to other platforms would reduce the company’s reliance on hardware, and with iPhone sales expected to start shrinking for the first time this year, diversification is exactly what Apple needs.
