I can understand that not everyone wants or has the time to keep explaining the same things to everyone (though I think there are solutions for that). Also, developers might have other priorities than polishing UX, especially if the software is a volunteer or hobby project. I wouldn't call those things "elitist".

However, what I absolutely believe is elitist is to intentionally design a confusing UX or value it as a "feature" because it will prevent certain groups of people from using the software. That was what the GP advocated for.
