My 2cents The Code of Conducts basically amount to a "code of wrongthink". This can be best described when some of their advocates, like for example in the Node project make respositories called "mansplain" and "misandry", or when speakers at OSCON are caught with mugs reading "male tears" and using the "#killallmen" hashtag, and are ironically ignored when you report these matters whatsoever.
More importantly many in the industry have taken af "extend, embrace, extinguish" mentality to open source, projects that have been initially open source have become monetized and controlled by organizations, which have no intention of allowing open governance or control over the code base, and use these sort of "code of conducts" to label dissenting opinions as "toxic" or heretical.
