Switch to a Fully free Operating System

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Depending on whether you want a distro that removes all non-free options from the start or one that gives you free options, or ways to only select free options, I'd add Gentoo to that list. Much like in other situations, it gives you the choice to have your cake and eat it too. You can select a list of licenses you want (with certain predefined sets), and override that list on a per-package basis if you want/need.
