This document (originally published on GitHub) contains additional supporting material for the claims in this post (published 1 September 2019), in response to a cease and desist letter from John A. De Goes that I received on 6 July 2020.

De Goes is the CEO of a Scala consultancy named Ziverge, the founder of a project named "ZIO" (not to be confused with the racist slur), and the organizer of LambdaConf, Functional Scala, and other events.

In the letter De Goes's lawyer claims that the post "specifically targets our client with the goal to publicly vilify our client" and threatens to sue me for defamation in a German court.

Please see also this post for more information about De Goes deleting the FCoP repository on GitHub shortly before sending the cease and desist letter.

The Fantasyland Code of Professionalism (FCoP) is a code of conduct developed by the Fantasyland Institute of Learning, an organization that was founded by John A. De Goes and is responsible for LambdaConf, a functional programming conference.

Many other people have written about the shortcomings of the FCoP as a code of conduct, including Christie Koehler, who calls it "beyond mediocre" and "downright dangerous", and Matthew Garrett (in an article titled "The Fantasyland Code of Professionalism is an abuser's fantasy").

The purpose of the post you're reading now isn't exactly to critique the FCoP, though, but to preserve some of the discussion surrounding it, since De Goes has recently deleted the FCoP GitHub repository and several other FCoP-related documents, in a move that seems related to the fact that he's currently threatening to sue me for defamation.

One of the claims in De Goes's cease and desist letter is that the following statement (published here) is false:

The FCoP was developed specifically in response to the 2016 LambdaConf controversy, and it's clearly designed to protect white supremacists like Yarvin.

De Goes's lawyer writes:

The FCoP is a code of conduct for professional communities that our client has created. The FCoP is clearly not designed to protect white supremacists.

I've provided evidence in another document that it's reasonable to describe Curtis Yarvin as a white supremacist, and that many other people besides me have done this, including journalists, prominent software developers (for example Erica Baker in this Inc. article), and one of his former business partners.

Update (25 July 2020): John De Goes has hired a lawyer to send me a cease and desist letter demanding that I delete this post. See my responses here and here for more details.

This post is a collection of links about John De Goes that show some clear patterns of behavior:

• De Goes defending white supremacists and misogynists.
• De Goes attacking critics and accusing them (especially women) of lying.
• De Goes engaging in targeted harassment, either directly (@druconfessions) or indirectly (e.g. via ClarkHat, a LambdaConf sponsor).
