I was busy in 2018, and didn't follow the discussions very closely at that time. As I recall, there was a desire by many that the GNU project adopt a code of conduct, and those people were disappointed when the Kind Communications Guidelines were released instead. But my recollection is that people felt the guidelines were insufficient, not that they were bad in themselves.
If you know of a post with detailed criticisms, could you please send a link?
