It's unfair to expect someone to work for free. In-app purchases are a common and reasonable way for programmers to sustain themselves while providing a valuable service to users. After all, programmers, like everyone else, need to make a living.

GP did not say they expecting someone to work for free. They took issue with the payment method and explained why.

If the app required payment by giving your name, address, credit card, and more to "Jimmy" (some person you don't know and don't trust) who will be contacting you to collect, and somebody said "I don't know Jimmy and I don't really trust this. I'd prefer to use a trusted method of payment" would you reply, "You just don't want people to make a living!" I would really hope not.
