This atrocious attitude is absolutely why software is such a hellscape of shitty UI and lack of features.
Normies should be eating our table scraps, not dictating how the software is written.
Normies learned how to drive a car. They can learn how to properly compute. And if they don't like the tech, they don't have to use the tech.
OSS is the last bastion of computing for people who know/like computing, because the armies of "designers" aren't selfless enough to donate their time like programmers are. And frankly it is better off that way, the prevailing trends in design seem to be all about limiting options.
Hard, powerful software over push-button appliances any day.
And, to use the car analogy, BMW gets away with this approach just fine.
