The title of the post is editorialized ("Walmart delivery drones selling photo surveillance service"), perhaps misleadingly.<p>The actual article title is "Walmart expands its drone-delivery service to reach 4 million households" and this is the relevant section:<p>> Walmart will use the drones to make money in another way, too. It said it plans to offset the cost of deliveries by selling photographs taken by drones to municipalities and local business, such as construction or real estate companies. The revenue will be split with the drone operator.<p>I wouldn't call selling selling drone photos of houses for sale to real estate agents a "photo surveillance service."
