The mentality of "that person said something I disagree with [on other media] and they should be banned here [on a random project that I don't have anything to do with] or else..." is incredible toxic.
If you don't agree with "assholes" writing code or using code that was written by an "asshole", you'll have a hard time using anything open source at all.
This is a common theme among proponents of codes of conduct.
See also Twitter's ban on many people, including Milo Yiannopoulos. He was banned for "violating the rules". But I've looked, and no one anywhere can point out which exact tweet violated which particular rule. Even more extreme, no one can point out where he said any of things he's accused of saying.
So... Twitter blocked him for "abuse", when there is zero evidence of such abuse.
I'll say this:
The more extreme the code of conduct, the more likely it will be broken by the people enforcing it.
CoCs are worrisome because they tend to emulate that behaviour, and I certainly do not condone overreaching TOS, but you can't equate those two situations. It's the behaviour of people vs. the behaviour of companies.
When you have such a legalese disclaimer as above, you don't need to lie about why you're banning someone. You just say "Under the Twitter ToS, we've banned Milo."
The fact that they chose to lie about the justification for the ban shows not only that the ban was politically motivated (and not based on reality), but that they are so incompetent that they can't even spin it in their favor.
Their bias is leaking. They don't really care about their own ToS. They don't care about following the rules they put in. They do care about banning anyone who they don't like.
I find such behavior unethical, and morally repugnant.
As others have posted here, some people pushing "codes of conduct in open source" end up violating those codes themselves, and abusing their authority. These people do this not only in open source forums, but in other places, too.
The underlying topic then, cannot be about the CoC. In reality, the topic being discussed is who gets to control the conversation. Along with that, who gets to decide what topics are acceptable. Not just which topics are OK for a list / forum, but which topics are "good think", and which ones are "bad think".
The question for someone running an open source project, then, is will your project be taken over by people who are pushing a particular ideological agenda, and who are using your project to do so?
My answer is "No.". Perhaps "over my dead body" is more accurate.
"We have adopted the Open Code of Conduct for the open source projects that we maintain, including Atom, Electron, Git LFS, and many others."

I have cancelled all my private repos with GitHub as I just don't like their ethics.
