You are fundamentally misunderstanding net neutrality. CloudFlare isn't an ISP. CloudFlare removing a website is analogous to Google removing a link or Facebook deleting a post. CloudFlare is merely a third-party internet service that companies are free to use or not. ISPs are different because they are much more prone to monopoly and abuse compared to CloudFlare. For a real life example, consider this: it's one thing for a bakery to ban Neo-nazis, and another thing for the public bus system. Granted, ISPs aren't public utilities, but they are much closer to one than CloudFlare, because CloudFlare provides a service that lends itself to competition. If you don't like CloudFlare, the upfront costs of creating a competitor pale in comparison to the costs of creating a competitor to Comcast or Verizon. To that end, CloudFlare banning Nazis is just as much the death of net neutrally as me getting fired for calling my boss a "kike" is the death of free speech.
