My long-time experience with software producers, be it professional or 'semi'pro, are usually willing to help out if something is not working 100% as expected. Seems you're the odd one out. Good luck with that.
The difference is, people like Nao and myself are neither 'professional' nor 'semi-pro'. We are hobbyists, we do it for the love of doing it.
Support is actively a pain in our collective rear. We make things because making them makes us happy. Having to spend time trying to pander to the expectations of others does not make us happy.
The best way I can sum it up is as:
Sarah: Give me the child.
Jareth: Sarah, beware. I have been generous up 'til now. I can be cruel.
Sarah: Generous? What have you done that's generous?
Jareth: *Everything*! Everything that you wanted I have done. You asked that the child be taken. I took him. You cowered before me, I was frightening. I have reordered time. I have turned the world upside down, and I have done it all for *you*! I am exhausted from living up to your expectations of me. Isn't that generous?
I got fed up trying to live up to the expectations of others, which is why I slowly stopped writing mods for SMF and when I learned the hard way of never writing anything for anyone else, to only write things I actually *want* to write. After all it's my free time I'm using to write things, surely I have a say in what I spend that time on?
