Citing from https://canoeboot.org/about.html

Libreboot no longer complies with GNU policy. In November 2022, Libreboot adopted a more pragmatic policy of allowing any board from coreboot to be supported, while reducing the number of binary blobs as much as possible. Although this may satisfy most people, there exists a minority of people who wish to still have a blob-free coreboot distro, like Libreboot once was.

Prior to November 2022, Libreboot complied fully with GNU policy in providing an entirely blob-free coreboot distribution. The rest of this article will go into a lot more detail, both on this and on the technical aspects, but the gist of it is this:

Canoeboot is, in spirit and in practise, a continuation of the old Libreboot project, prior to that policy change. It maintains sync with Libreboot as closely as possible, while removing any and all non-free code, and disabling/removing any code that could possibly handle it (for example modifying coreboot so as to never add microcode updates or download blobs, even if told to by coreboot configs, since the upstream coreboot project is otherwise engineered to handle these if requested by the user).
