CloudFlare uses Comodo certificates–millions of them, I imagine–and that probably makes them a commercially significant Comodo customer. As a CloudFlare customer with a Comodo-issued certificate, I hope they’ll try to convince Comodo of the value of doing the right thing.
Comodo is just cross-signing CF certs[1] because the CF Origin CA is not yet in browser trust stores. GlobalSign and Digicert also cross-sign CF certs.
CloudFlare's Origin CA was created exclusively for communication between CloudFlare and backend servers. I haven't seen any kind of announcement mentioning that CloudFlare has plans to operate a public CA and apply to root programs.
