While Cloudflare has introduced many industry disrupting features, the pace of innovation isn’t that fast if you look a bit deeper. For example, it only took like three years or longer for domain registration to be available for new domains (it was only transfers until then). The reason given for this on a HN comment was a non-answer. If you visit the forums on Cloudflare, you’ll also see different kinds of billing related issues that, while they may be a bit complex, are not responded to as well as one might expect.
Nevertheless, Cloudflare is doing a lot of stuff that will prod the competition to wake up (or just let them die).
