Yes, I believe Cloudflare shouldn't have interrupted their contract with Stormfront, or anyone else, for the reasons that they don't like what these others are publishing. That KF is a horrible place for horrible people should simply not be Cloudflare's concern. A company that is offering web hosting or DDOS protection services is too far removed from this idea of "publishing" for this to make any sense. I am not even necessarily against things like YouTube removing Alex Jones' videos - but this type of content validation needs to stop early. If you believe Cloudflare shouldn't do business with these people, neither should their ISP, nor should Github or Nginx or wherever they get their code from, and soon you'll say that they cleaning services company and their accountant should similarly stop providing service to such an evil organization (without any legal recourse, of course). And to be clear, I don't in any way sympathize with what KF is doing (assuming what you are saying is true, which I do believe but have not checked myself). But suing them or at least seeking to alert the authorities is what you should do, not complaining to Cloudflare about it.
