This is just repeating a common meme. Blender's UI layout and organisation is fine, but this is a UI library. There's nothing wrong with blender's UI technically, in fact its pretty decent overall
I absolutely detest it (TBF I haven't used it for the past ~2 years) but I also recognize that it's an incredibly difficult problem space that lacks an obviously good solution, the tool itself is inherently and irreducibly complex, it's a free project with extremely limited resources, it's been consistently improving over time, etc, etc.
