If another company did what Cloudflare does and homogenized tons of requests behind them, you can bet Cloudflare's CAPTCHA systems would block them in a second.
I have zero respect for Cloudflare's inability to answer criticisms about what they do, about their constant deflections from simple, straightforward questions, and the fact that they do to others what they would never accept anyone else doing to them. It's hypocrisy in the service of trying to become a monopoly by re-centralizing the Internet.
Don't believe me? Go ahead and look for examples of Matthew Prince addressing concerns that much of the non-western world can't access Cloudflare fronted sites because of Cloudflare's "reasons". When you don't find any that have more than just vague platitudes and handwaving, imagine how you'd feel if you were one of those multiple billion people.
