Why? So the i-NSPIRE could be at twice the price, remember when the original iPhone came out & all the exist Bluetooth devices wouldn't work with it, yet miraculously once the devices got licensed to work with the iPhone there was no problem with them. Apple did to Bluetooth what DJI is doing to Apple...
The more I think about Apple buying DJI, the more I think it would be like having a sharp pointy metal thing being twisted into my head.
