The challenge is that when you're building software for developers, they already know how it must work. Do you mean that what you built didn't worked as it should? I don't understand, I've paid multiple times for tools that I find useful, even if they weren't perfect. This misconception has been promoted by companies with an interest in promoting their platforms, using the expeditive procedure of subsidizing (often inferior) tools, with the collateral effect of making impossible for tools vendors to compete. But by no means it's a law of physics. Make something programmers want. It's weird how little have the tools improved in twenty years.
