I don't think so. Maybe I'm misunderstood, but the "I use Arch" meme was meming on the fact that using Arch was a flex, like it's harder to get into, and you're a true blooded Linux user if you're using Arch.
Whereas, Pop_OS is kind of the opposite. I'm fairly new to Linux (been using a Linux system as my daily driver for about a year), and Pop_OS was recommended as a beginner-friendly distro. Plus, it worked well with Nvidia cards with minimal effort. So maybe it seems like a lot of people are using Pop_OS and are bringing it up, because there are a lot of newer Linux users.
