Most owners buy one then realize: - they can't legally use them wherever they want them and there are finally very little areas you can really use them - they can't use them in FPV mode or without seeing the drone.

Then decide if they want to break or follow the law. Most people not wanting to break the law will let the drone collect dust after a handful of use, those that break the law will eventually lost it at some point or get bored.

I think the only people who really keep using them are travel vloggers and they have sometimes issues at border control and usually need to ask permissions and pay taxes to be able to fly and record stuff near a particular place. Usually they only get permission because they are well known and would boost tourism.
