Agree with the sentiment but trust in software is at an all time low and you have to work against that.
An example success is the developer of Superwhisper. Crazily responsive online, always polite, explains features with blog posts and videos, has a fan base of creators on youtube who fill in gaps in the docs and talk about creative & cool uses for the tool, and where possible the software provides local only ways to get work done.
If going closed source (which is fine) you could completely copy their strategy.
