Probably worth noting: The author writes the article as though the latest experiment "solves" the issue.
A more nuanced description (which is not exactly quantamagazine's forte) would note there is a conundrum about the proton size. The article describes a measurement that falls under "spectroscopic methods" in the wiki [1].
Why eg scattering measurements should yield a different value is not at all clear.
