You got that wrong. No one was censored by CF, because you dont need CF to have an internet appearance. If anything, it's the DDoS attacks that are censoring KF. But in the end it just got more expensive for KF to speak.
CF outright blocked the KF domain, they didn't just rescind DDoS protection.
and deliberately not protecting a paying customer as they are attacked by DDoSing criminals is just censorship by another name. it's a critical piece of infrastructure; large sites just can't survive on the modern internet without it. it's like if the police and fire services announced they wouldn't protect a specific house from roving packs of arsonists.
Well, no, that's not how it works. They stopped business with KF by not forwarding traffic to the protected/secret origin anymore, thats how reverse proxies work. The owner of the domain is free to update their DNS records and point it to another CDN or even the unprotected origin
