Yep the ME deactivation comes from the project of Nicola Corna
https://github.com/corna/me_cleaner
I used it as well in the latest version to deactivate the ME and remove
almost all the partitions in the ME region in my laptop.
Regarding the Purism, I actually found citation in their blog of the sources.
For example here
https://puri.sm/posts/reverse-engineering-the-intel-management-engine-romp-module/
They cite the russian developer and as well the me_cleaner project.
I also noticed in the last pull I did from the coreboot git repo a huge
amount of push from them in the coreboot project.
