Is Arch the most popular Linux distro at 0.15% of 1.95%? What’s missing here? Steam OS?
A couple of things -- yes, SteamOS is by far the most popular Linux distro and it was left off this part of the list, and also Arch is the most popular because it's a rolling release distro, so we're all running "Arch Linux" no matter how far behind we are on patching our system. Ubuntu would probably come out on top if you bundled every other version besides 22.04.3 LTS together into one line item.
Here's a screenshot of the Linux breakdown with a few more entries (though most are still bucketed under Other). SteamOS alkone is almost half of Linux deployments.
