Your comment is much more rage-bait than the article.
Universal isn't a way we describe numbers. You meant to say dimensionless. Pi is dimensionless constant because it describes a relationship between two measurements of a dimensionless unit circle.
Pi is expressed as a pure ratio between two other dependent numbers. Dimensionless values are special because they don't rely on any particular measurement in any particular location, lending to your misconception of "universal" constant.
This article explains how a particular dimensionful constant (g, the strength of gravity on earth's surface) is related to pi.
They are related because the dimensions in question are both derived from dependent properties of our planet. These dependent properties will be found on any other sphere floating in space if they are derived in the same fashion.
It's good to thoroughly or even marginally understand a topic before adopting a dismissive and authoritative argument against it.

They probably really meant to say “universal”, since dimensionless values are a less interesting category that includes… well, every number. Pi shows up in math without having to parameterize anything, making it universal in a way that even physical constants of our universe aren’t.
