Normally in this rant I specifically note that non-software technical people are still technical. For genuinely non-technical software, what are the most popular end-user facing FOSS-developed applications? Firefox, signal, blender, Inkscape, Krita maybe… most of those are backed by foundations that pay designers and in Mozilla’s case, actually do a ton of open usability research. I don’t believe Inkscape does but they do put a ton of effort into thinking about things from the user workflow perspective and definitely do not present all of the functionality to the user all at once. Blender, at first, just made memorize a shitload of shortcuts but they’ve done a ton of work figuring out what users need to see in which tasks in different workflows and have a ton of different purpose-built views. For decades, Gimp treated design, workflow and UI changes like any other feature and they ended up with a cobbled-together ham fisted interface used almost exclusively by developers. You’ll have a hard time finding a professional photographer that hasn’t tried gimp and an even harder time finding one that still uses it because of the confusing, unfocused interface. When mastodon stood a real chance of being what Bluesky is becoming, I was jumping up and down flailing my arms trying to get people to work on polishing the user flow and figure out how to communicate what they needed to know concisely. Dismissal dismissal dismissal. “I taught my grandmother how federation works! They just need to read the documentation! Once they start using it they’ll figure it out!” Well, they started using it, didn’t have that gifted grandmother-teaching developer to explain it to them, and they almost all left immediately afterwards.

Just like human factors engineering, UI design is a unique discipline that many in the engineering field think they can intuit their way through. They’re wrong and if you look beyond technical people, it’s completely obvious.
