Are you suggesting that the developers who’ve been doing this for 20 or more years don’t understand their market or what it takes to develop product and make a living at it?
This is NOT a new market, there’s been airports available for sale by developers since the early 80’s now that I think about it, when I think back to some of the addons I have in my closet.
I had some addon scenery for the old Sub-logic version. I remember being able to buy airports and planes for FS95, and on and on. The ones who are still around know what it takes to make a living. And… there’s plenty of people who do this for free, like me
