I see. I think commit message to the patch gives an answer to your question, I will copy commit message here just in case you maybe missed it:
For now link to coreboot's one, in the absence of our own.
It is always possible to create our own later, if desired, but meanwhile we can share code of conduct with coreboot. We do have the same servers and infrastructure anyway.
It can take some time to produce our own code of conduct, and yes now we have 3 threads on the mailing list, and maybe we'll have even more. Meanwhile, between today and the time we finish our code of conduct, we can use coreboot's one.
There is no demolition, if you look at the patch it adds a new page and does not remove anything. Also as I said we now have 3 threads on the mailing list. So... I am not entirely sure whether your reference applies. But now I know what your favorite book is :)
