With that recent post about chrome os not counting as a distro of linux. It does bring a good question, what is a distro of linux?
If Linux is just a kernel then android and chrome os are Linux. Bur no really considers android a distro of linux. So linux is more then a kernel.
KDE say that neon is not a distro but doesn’t really why neon is not but kubuntu is.
Idk I know they don’t fit into the usual open source box of Linux but I’d consider Android and ChromeOS as Linux distros, a distro is just a collection of software distributed with the Linux kernel as far as I’m aware. If someone doesn’t consider them “Linux distros” it’s probably due to the proprietary nature of some of the software surrounding the kernel. No idea why kde thinks neon isnt a distro when it literally is.
Edit: in the case of chrome os it’s not even just built around the kernel, it’s based on a distro.
