I am a bit naive. Who is paying who in this contract? What is either side getting out of it? Why can it not just be a pluggable DNS provider situation and let CloudFlare compete with anyone else for opt-in (including extra privacy features if so desired)? Also curious, why would CloudFlare offer stronger privacy protections for one type of user and not another...what is CloudFlare getting out of the lesser-protected users since it is clear everyone is not given the same treatment?
