Also, it's not end-to-end encryption, but from client to CloudFlare - so "your" certificate may have 20+ other CloudFlare clients' domains included.
If you are using CloudFlare it makes it easy to set up, and +1 to them for making it available on all their plans. However, they're not a CA (they use Comodo?) nor a place to get free DV SSL certs (on its own).
On a personal note, I'm not surprised at all by this news. I received and installed a LetsEncrypt DV over the weekend on my Ubuntu/nginx/node DigitalOcean Droplet. So easy - no way a CA can justify selling DVs anymore.
