Kiwifarmers can call each other on the phone, stand on a soapbox in a park, print pamphlets and distribute them. They are still free to say whatever they want to whomever they want without fear of a Government throwing them in jail unless they break the law. Anonymous posts simply allow Kiwifarmers to say things they would likely never say to your face. Cloudflare simply chose to not allow their paid for service to support this behavior. Big deal.
