Just looking at the chart, your article makes a case that minimum is much better than maximum, and in fact if you report one number, the minimum is the best number to report (in that particular example).
If we go into details - sure, 1 number is not ideal, but neither is the confidence interval, because people will assume normal distribution for them. If you report 2 numbers, perhaps instead of confidence interval (which falsely implies normal distribution) it's better to report the mode and the median.
