I do not think the design "annoyances" of Far East industrial products are matter of an "lack of professionalism".
It is about their "perception of beauty". It is a fully different culture in this regard, when comparing to Western one, indeed.
We say their products look like "Christmas Trees" (lot of different lights, colors, rounded shapes, bubbles, fonts, crazy shaped buttons, shiny surfaces, mirrors..). They simply like that..
Look at their cars, for example, and compare their design, for example, with a BMW.
The same with o'scopes, it seems.
PS: see below Western vs. Far East perception of Beauty (imo)
