Because doing it without a wire was, until relatively recently (5 years), something only iPhones did well, or at all. Consumers have been used to cables for decades, so they demand something that just works in this area. The same goes for data. Apple tried Thundebolt and it failed, because consumers already have something that just works and is compatible in this area (USB), and they wouldn't let go of it. Wifi streaming is relatively new, compared to cables, but once we get used to it Just Working, there's no going back for consumers. It's almost the same with Wifi voice calls, where, unfortunately, consumers don't demand something that just works, but are left with two incompatible protocols (FaceTime and Hangouts, or whatever Google's version is called these days).
