I agree, it's not as simple as yes/no. I find that creating new software usually is not that expensive, but maintaining it is: dependencies update, new language versions, new formats, new requirements, etc. In my experience burden of maintenance is often more costly then budget for initial development. Maybe that case could empower more people to consider contributing to open/free projects.
