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.

yeah, no you have a misconception of what risc-v is.
Risc-v is an isa not a chip. the isa is open, available to anyone.
Implementations of risc-v (actual working designs) are usually not open. They are just guaranteed to be able to execute risc-v instructions.
So risc-v is neither more nor less vulnerable to hardware backdoors than any other architecture
Thanks for the clarification!
