There is a You tube link to the 2017 talk Dr. Lenny Jason gave to the Ethical Humanist Society of Chicago on "Understanding Unexplained Illness: From Knowledge to Action"
At approximately the 29:30 minute point, Dr. Jason talks about the ME community's negative reaction to the term SEID; some in the audience laugh at this term.
Please see under "Talks and Interviews" on MEpedia's page about Dr. Jason, and his talk on January, 2017:

ETA: when I checked the You tube link I posted here, there are two differently timed versions of this talk going at the same time. Attempted correction - it didn't work. Therefore, I removed You tube link.
ETA #2: Dr. Jason's talk is excellent: covers some of the history, and does delve into criteria.
