Base Community Distros

Since Red Hat made their recent decision, there has been a lot more talk about people wanting to focus on communiy-based distros instead of corporate-backed distros.

I was trying to think of how many active, stable, user friendly base community distros I know about. When I say a "base" distro, I mean a distro that's basically the base for its ecosystem. For instance, Debian would be a base distro because it's the base of its ecosystem. A community distro based on Ubuntu wouldn't fit what I'm talking about here because Ubuntu is a corporate distro.

So, there's Debian.

Arch is a base community distro but it's not user friendly to install, but there are more user friendly varieties of Arch available like Manjaro and a few others.

All of the other base distros I can think of are either corporate, or aren't particularly user friendly to install. Care to add your thoughts to the list?
