Where is Twitter Music for Android? With today’s launch of Twitter’s new music discovery platform, the company has again made a move to sideline the install base of around half of the U.S.’s smartphone audience by failing to deliver a native application for users of non-Apple devices. It’s a strategy that still remains prevalent among tech companies today, both large and small. The companies’ reasons vary: for many smaller startups, there simply aren’t enough developers to build for iOS and Android simultaneously. Meanwhile for others, the iOS-first decision is more of a strategic play.
