I'm happy to answer any questions around this! We've been working on this since update since we launched the product last year, so we're excited to be able to share it today.
Will all software shipped with the hardware when ordered with GNU/Linux be Free or will there be non-Free software such as the BIOS/UEFI?
EDIT: I just realized that you cannot order this laptop with GNU/Linux pre installed. I was mistaken.
We've seen distro preference be too broad to make pre-loading efficient. Instead, we ship DIY Edition with no OS and publish guides for how to install and optimize the most popular distros. Our embedded controller firmware is open (see https://github.com/FrameworkComputer/EmbeddedController), and we're working with some community members on attempting a coreboot port.
