Sure, they pay for it because it solves a specific problem, and it saves a lot of time. I care about the product because I put a lot of work into it, and it's a "creative outlet". I enjoy making all the decisions and having the freedom to work on whatever I think is important. I'd keep working on it for a while if I didn't need to worry about money. But I also really like the idea of a "finished product" that doesn't need any more work. That's what I'm aiming for, although I'm probably a few years away from that. I wouldn't keep working on it if it failed and no-one was using it. I would just move on to the next project.
