Yes—we can see it's a suboptimal design on its face.[1] Bunch of repetitive dots and lines, with misleading clues. Not everyone is going to respond to it the same way of course. Some folks don't bother with clues.

The main point is that this problem has been solved already, better and in the past, by products delivered to tens of millions of seats. Merely copying prior art would have sufficed.

Responding with, "I found some non-techies who didn't have a problem" is not a direct response to the idea that the design could be improved. Folks can persevere and ultimately succeed through poor designs... in fact we all do it every day.

Some of us would like to use products that are a little more thoughtful than the bare minimum attainable-through-perseverance functionality, however.
