Hi Thvie,
The EC firmware is indeed non-free, as it is on all other
Libreboot-preinstall sellers too:
https://libreboot.org/faq.html#ec-embedded-controller-firmware
What you're purchasing is a system that has a free BIOS replacement
(Libreboot) and free operating system (Trisquel GNU+Linux). This is the same
as other Libreboot X200/T400 sellers.
swiftgeek, who I work with in #libreboot IRC, is working on a libre EC
replacement on these laptops, but the work is not yet complete.
Generally, the systems that Minifree ships are in excellent physical
condition. We always ensure that laptops are of high quality.
