The link you attached is 2015 and the information not completely true. They
do ship with coreboot when the author of the article was pretty sure they
would not do. I saw their hardware listed on the coreboot repo.
They deactivate the intel ME as I did. They cite the sources of the
me_cleaner.
Personally I consider free (libre) a computer where the ME is deactivated and
where coreboot is installed. That is enough for me.
This allows to push to free all the recent hardware.
I think that the FSF and libreboot will be pushed to accept the new hardware
since soon most of the people will consider having all the ME code erased
irrelevant if the ME is deactivated.
I am happy I didn't purchased a new(old) x200 laptop and I instead learnt how
to partially free my modern one. Now I am studying coreboot and if I can port
it to my laptop.
