I decided I will include the emails with editorial comment (like you suggest).
Also, thought you might be interested...
I did some more digging (see https://stacker.news/items/694651 for write up). The upshot:
. the Wei Dai emails seem legit to me
. Matonis email...I'm still not sure
. I reached out to Dai, Matonis, and NakamotoInstitute.org
. heard back from NakamotoInstitute, essentially they said they had a policy since 2014 to not include personal emails for fear of possible privacy issues and/or accidental doxing, but that they're reconsidering now that 10 years have passed and many emails are in court records
