This really isn't the right place to have the discussion on this.=/

K/community is our source of truth and it points to the CNCF CoC. It's been hosted hom the site as a convenience. There was a long comment period open to the community at large to discuss their proposed changes with multiple announcements being sent to call for comments.

Instead of keeping a copy in the contributor-site and needing to update it once in a while, I think we should point to the source of truth.
