I agree, I saw the author mention for $25k you could have 1000 keys. I immediately though that is not nearly enough. Given the sheer volume they have, they would start putting a picture together very quickly of ip/key/sites. There is no where near enough uniqueness. I also thought the idea of the key exchange being fast was a red herring. That's a bad thing. If I'm them I'm paying attention to how long from prompt to exchange it takes a human to touch the button. On my own setup my key is on my laptop, which is in a dock. I must stand up and tap it over my monitor. It's just a few seconds but it's a) consistent in timing b) not < 1s. Imagine the aggregate timing data they have. Overall they make some good points if you are teeny tiny player and ignore completely the scale cloudflare is operating at.
