I can speak only to the Android platform, on which you receive notifications when there are updates to either an app or the operating system itself, which give you a description of what is happening and why it's taking place. Then once again, even after the implementation of the updates, you can make the decision within the permissions to deny access to Bluetooth and to deny access to location information. So even if there is the functionality, you can still turn it off on your device.
