People do like to complain.
It is one thing buying a house near an airport (usually at a lower cost to compensate), and then complaining about it.
It gets a bit woolier when you've lived near a quiet field and then the number of movements significantly ramp up.
Air tours are a valid and relevant service.
Different countries treat the service, particularly in sensitive areas, differently, and control the different types of activities so the area isn't spoilt by noise or pollution, or even people for that matter.
There comes a point where a service can become pervasive, and starts to affect the enjoyment of the area, not just for residents but also other visitors.
The more popular the place, the more intrusive is the problem.
Telling people raised in a town, most who have been there a long, long time, that they should go live somewhere else so you can make a buck is ludicrous and the sort of tosspot attitude that some (not all) operators display.
"reasonable" is an abstract concept and something two sides will never agree on, but you would hope that sensible people can find some form of compromise where they can all co-exist.
Conflicts will only increase as development encroaches on airfields, environmental impact becomes top-of-mind and these types of services become in greater demand.
In a post-Covid world, of course.
