> What secret and hidden, nefarious things could those reasonably be? Collecting photo and video footage combined with GPS data without the explicit consent of the owner would be the biggest one, IMO. That would be a great way to build maps of areas that aren't visible from satellites, or to get more detailed imagery than a satellite, or to build full 3D maps of areas using photogrammetry or similar. Just the GPS data could also be very useful, as it would be a map of the space that drones are likely to be able to fly through. If someone has a 3D map of areas where consumers successfully flew drones, seems like that would make it much easier to send semi- or fully-autonomous drones through there too, if the area were of interest. The US Navy has a problem with mystery drones surveilling their ships, so it seems reasonable to assume that folks are doing the same with sensitive facilities on land. Maybe it would even be useful for plotting flight routes for cruise missiles, so they can stay as close to the ground as possible? Capturing wifi access point information, like some mapping companies have done, could be beneficial to an organization that doesn't have traditional mapping vehicles. Same for any other radio signals that the device can pick up. All of that is more or less passive, with the exception of sending the data somewhere. There are a lot more options if the manufacturer is willing to be more aggressive and risk someone noticing that their products are behaving oddly.
