I'm not well off by any means but I'm happy to save and pay $60-80. I do wish people would appreciate how much time, effort and money is invested in these modules and similar software developments. I've spent $70 on call of duty which took a few days to finish yet am still flying around and using the A-10C since it's early release, many years later.
For most of us, these modules are the closest we'll ever get to experiencing flying these aircraft. Millions are spent training real-world pilots along with countless man-hours, we get a small taste of that for the price of a single night out. When I see similar amounts being charged for some console games, I appreciate that many companies making specialist material such as ED/Belsimtek etc, could likely make much more were they to divert their skills to those platforms. As I see it, $80 is not only an investment to my hobby, but a small thank you too.
If people don't want to pay the higher amount, then there is the opportunity to buy them pre-release or wait for a sale. I think the developers have been most fair in this regard.
