Cloudflare's license grant is quite appropriate because the whole point of a CDN is to make copies of your content and cache them closer to your users. Cloudflare also provides numerous tools that modify, and create derivative works of, your code and images on the fly. Vultr on the other hand is just a bunch of compute/storage resources hooked up to pipes. They have a rudimentary CDN offering, but that's about it.
