I don't think this argument is well stated, so I'll give it a shot. CloudFlare is very basic infrastructure and there are a handful of companies providing such infrastructure, thus a group can be effectively deleted from the Internet if these companies decide or are pressured to do so. (Example of pressuring: Patreon dropped some accounts at the behest of Mastercard.) So maybe the real question is, "does this notion of the integrity of DNS extend to other basic infrastructure services?"
