Actually it's kinda smart. cloudflare-ech.com is going to be blocked by the Great Firewall and every other state-level filtering apparratus approximately ten nanoseconds from whenever this blog was posted. Cloudflare needs a bunch of not-objectionable-to-governments sites in the anonymity set. For these sites, being in the anonymity set has a cost (a few of your visitors can't get to your website) but zero benefit. For the free plan customers, Cloudflare kinda doesn't care about slightly pissing them off. They aren't paying anything. As long as they aren't all so pissed off that all of them leave simultaneously, Cloudflare is free to take advantage of them for both benevolent (as here) and nefarious (other situations) purposes.
