Linus' thread: (CW: bigotry and racism in the comments) https://social.kernel.org/notice/AWSXomDbvdxKgOxVAm (you need to scroll down, i can't seem to link to the comment in the screenshot)
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.

Free software is, at its core, about the users having control over their own use of the software - the software isn't controlled by some owner and licensed by the users, but instead all users have equal ability to understand and use the software. If you consider communism to be political, then free software is political, because free software is communism in its purest form.
