a bad graph about Hubble discrepancies

Here is a picture seen in a Nature Reviews Physics paper I came across, on  the Hubble constant being consistently estimated as large now than previously. I have no informed comment to make on the paper, which thinks that these discrepancies support altering the composition of the Universe shortly before the emergence of the Cosmological Background Noise (CMB), but the way it presented the confidence assessments of the same constant H⁰ based on 13 different experiments is rather ghastly, from using inclined confidence intervals, to adding a USA Today touch to the graph via a broken bridge and a river below, to resorting to different scales for both parts of the bridge…
