DJI Drones to Warn They're Near by Sending Wi-Fi Signals to Phones

I'm starting to become more and more suspicious when tech companies offer free features out of the blue, so forgive me for asking this question:

Could this end up being a plausible "serving the customer" reason for DJI drones to start collecting and reporting Wi-Fi signal, location, and temporal data back to the parent company on a regular basis? (That's with or without the matching phone app being installed and running.)
