Yes but we have hundreds of regulations and laws to protect people from car-death. Currently there are no real laws to protect people from drones being used to take down a plane, deliver a bomb to a target undetected and generally cause mayhem. The potential for drone technology to be used for evil is just mind boggling.
I think it's more that continually evolving software updates bloat and eventually render the device sluggish. New code is written to take advantage of new hardware, at the expense of owners of the older models.
