Apple seems to have driven the cost of all (mobile) software to 99c or free, roughly. How can anyone really make any money just making something solid and usable without turning it into a "service" or something at that price? And I as a user don't want any of that stuff because I don't want a service to lock me in, I want to pay up front for something good and leave it at that.
Pro/power user apps still cost a bit. Apps like Procreate and Luma sell for >$10 and seem to have great sales. I guess the issue comes when you have sold your app to almost everyone who is willing to buy it and then you are unable to make any more sales which forces you to either go to subscription model or to create a new listing "Procreate 2" to charge everyone again. Both of these options make people pretty upset though.
