I don't think pushing users to Bluetooth is a ploy to get more users to use Bluetooth. Toggling Bluetooth off only means the user-land applications can't use Bluetooth, the system might still use it for location-based services, if those are enabled. The "Find My" network would probably do a similar thing of piggybacking on such a feature.
I always wonder if the removal of the headphone jack was a ploy to get iPhone users to use Bluetooth so the find my network worked better..
