> Apple mercy-killed Adobe Flash, we should be asking they do the same to Bluetooth.

They won't, because it turns out Bluetooth is the best thing we have at "discover nearby devices". Guess how Apple TV/screen sharing detection, iPhone hotspot detection and configuration, AirDrop and a whole host of other features work without communicating via some cloud mothership? They are all using Bluetooth to do detection and negotiation to a high-bandwidth link!

Amongst widespread radio communication mechanisms, there are only NFC, Bluetooth and WiFi. NFC is sometimes used to provision wifi passwords, but it's short-range to the tune of a few cm tops. WiFi has discovery, but nothing in the protocol to make sure initial conversations cannot be eavesdropped, and low-power wifi stacks are hard to do, in contrast to Bluetooth with BTLE.
