It's a reasonable question -- and I'd consider it another argument for the "paid upgrade" model not to have died. That makes it possible for users to hop off the bandwagon, while still providing some level of recurring revenue from existing customers for developers. I'm not sure how to really address that in a subscription-based world, although PocketCasts seems to be pursuing a pretty good approach here: you can use the app for its core functionality without subscribing at all, and the subscription price is pretty reasonable. If you want Office 365, where the cheapest price is $70/yr, the calculation might well lead you to "let's see if Apple Pages or LibreOffice can do what I want instead."
