In fact I think it more important to point out that the incident proved they can and will do such a thing, and will have less of an argument should someone stick a piece of paper to their head and tell them to do it more often.
I like cloudflare and appreciate all these cool things they are doing with with other's (Google's, Micorsoft's and Baidu's ?) money... however the old playbook of get big and entrenched then start to bleed your captive customers is getting rather old.
Wall street pressure has made godaddy much worse in my experience, and I have seen nothing that says cloudflare has done anything to prevent these things from happening again.
Whichever registrar is keeping stormfront as a customer is likely more resilient. (would like to know which (tucows?) reseller is the one.)
As I have mentioned elsewhere, I hope cloudflare is already setting up ways to split their company into cloudflare US, cloudflare CA, cloudflare UK, cloudflare JP, IN, etc etc.. as I think it's the only way to prevent mass takedowns that are likely coming in the future.
