That’s a really weird way of framing a hobbyist who isn’t being paid using their free time to code what they feel like coding. It seems to me that people who show up and make demands about what someone else does are literally attempting to dictate how that person spends their time. Someone coding what they want, rather than coding what other people want them to code, is just… independent? Autonomous? Do you really think that someone spending their free time how they want to constitutes being a ‘mini dictator’?

It sounds to me like some end users like to have power over others and feel entitled to dictate how those who make the things they use spend their time.

Personally, my suggestion to people with that attitude would be that they learn to make what they want themselves rather than demanding that others do it.
