The projects that have those codes of conduct are the ones where any reactionary maintainers could be overruled. You have to look to the projects that have never had codes of conduct, the old guard and Incelie techbro spaces. Brave’s CEO is a homophobe, for example. This has been known for years, he still makes homophobic comments. Brave does not have a code of conduct or community guidelines. And basically anyone that notices and tries to address an issue like racism or transphobia with a repo suddenly finds a mass of reactionaries coming out of the woodwork.
