Jeremy Runnells affirms he wrote the CES Letter and it was not "crowd sourced".
u/kolobot, "Evidences for the truth claims of the BOM you may have never heard of.", Reddit, December 15, 2021
Author here. Know this wasn't ill-intentioned but let's stop feeding into the apologetic bullshit that the CES Letter was "crowd sourced" on Reddit. It wasn't. https://cesletter.org/faqs-common-attacks/#fake
I wrote that entire document myself from start to finish from March 22 - April 13, 2013. I asked for feedback on Reddit twice on my 90%+ completed drafts but none of the comments were useful or of substance to be constituted as having helped me write the letter.
Happy Festivus!
