You can run a free OS pretty effortless, but when wanting 100% free software, you have to dig deeper and replace the proprietary BIOS firmware.
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.

Star Labs' take on the matter.
Furthermore, if one is sensitive regarding their cybersecurity, then one is likely to adhere to the zero trust security model and thus choose to simply not trust; which would include the closed source BIOS. coreboot, on the other hand, at least allows one to audit it themselves. As Linus Torvalds has been approached for implementing backdoors, it should surprise nobody that (some) of the vendors we buy our devices from have been as well and thus our BIOSes might not have been as safe as one would like to believe. Qubes OS, the most secure OS on desktop, shares the view that coreboot is preferred over closed source BIOSes due to reasons related to trust.
It seems silly to be distrustful of proprietary BIOS firmware without having the same skepticism of the actual hardware.
I wholeheartedly agree.
Though, this shouldn't stop one to pick their fights and savor the wins. The defeatist mentality is our biggest enemy, we will not be victorious in the end if we don't resist.
Let's hope an excellent implementation of RISC-V with eye for open-source, processing power, efficiency and affordability comes out so that we're not limited to the expensive (but otherwise excellent) Talos II by Raptor Computing Systems.
