Privacy is a legitimate concern, but those concerns should be brought up on the legislative table. Here is the U.S. people think they have privacy, and rights to privacy, but in most situations that is not the case. They have a right against "unreasonable search and seizure" but unless their particular state has enacted specific privacy laws they have almost no right to privacy. Credit card transactions are monitored by the IRS, all electronic media communications are captured, reviewed via sophisticated data extraction programs, and saved by the NSA and other agencies, police departments use license plate tagging to establish travel history, cell phones capture a constantly updating stream of location history, and various law enforcement agencies employ faux cellular repeaters, causing cell phones to "think" they are linking with a legitimate repeater, to extract almost everything from the cellphones of everyone that links to the repeater. In some cases they fly aircraft with such devices to cover a larger territory. Then we have the larger cities that use a multitude of security cameras that capture the faces of people that are then loaded into a facial feature recognition database for future reference. Anything that hits the web is wide open and has no possibility of not being back tracked to the point of origin. Your phone, desk, or laptop has a MAC address that is particular to the device that is easily tracked. Topping all that are the numerous surveillance satellites employed by our governments and they are absolutely watching a great many things that we do. Where do people think Google obtains their satellite views, which, BTW, are resolution controlled by governments? Google and FB are noting everything you do on their sites or with their search engines, and selling that information to anyone that wants to buy it. YouTube maintains your viewing history and no amount of deleting items viewed eliminates that history from their database. Those that travel internationally have their travel history stored in another permanent database. All of this stuff can be linked and accessed at any time by those with the power to do so.
So there is indeed a privacy issue, but the problem is not one significantly applicable to the private use of consumer drones. It's on a much larger scale, one that needs to be reigned in by 'the people" at the national/international government levels. That's not going to happen because governments are nothing without a means to control, and information is but one of many means to control.
