I suppose the thing is, I personally wouldn’t care much if anyone else used it or not, my itch has been scratched. If someone else finds it of use, great! If they need changes, they’ve got the code and can get crackin’ on it themselves. Or, they can pay me to do it if we can agree on a price. Outside of that I have no expectations.
That’s definitely a healthy way of dealing with that.
But with this way, something like Linux, Distros, Firefox, Blender or LibreOffice would have never happened. There are those who want to build retail-level open source software, mostly out of idealism, and then you are stuck between a non-monetizable rock and a toxic hard place.
But I totally agree with you, unless you are super idealistic, your way of handling it is probably the most healthy one and the one that will cause you the least amount of trouble. And it’s also what I do, except when I sometimes do get idealistic.
