      Yes, you can disable DoH in Chrome, Firefox and other legitimate applications by using Group Policy, but there is also the aspect of malicious applications or poorly coded applications that don't provide that facility or don't respect it for malicious reasons.

      Or somehow the default always favours one party, and somehow you keep ending back up that default. You can keep turning off location tracking, but somehow it never sticks.https://fortune.com/2018/08/21/google-location-tracking-lawsuit-ftc/ …

      Are your arguments so weak that you have to play the "malicious ulterior motive" card? Frankly, it doesn't even make sense, "I don't trust anyone to honor the setting, so you should never even give us the setting"?

      Once your company has a track record of not ignoring these settings or accidentally monetizing/sharing things they said they wouldn't your argument would be credible. Until then we wait. You are aware of where you work? I sometimes wonder.

      Please stop with this nonsense Bert, I'm not questioning your or PowerDNS motives. Let your arguments stand on their own if they're strong enough.

      You can look at our privacy credentials all you want, they are sound. Track record and business model matters when someone attempts to centralize even more internet on themselves.

      🙄 You're right to be worried about this Bert, the argument for DoH is so strong and your silly personal attacks are so weak that the days of DNS snooping products are surely numbered.

      1.1.1.1 and 8.8.8.8 have turned off all their logging? Are their days numbered?

      The queries have to go somewhere by default. I think that optimally, that default should be DoH to a RR of local, vetted providers who have made strict privacy commitments. A single vetted provider is not as wonderful, but sure is a better default than whatever the DHCP tags say.

      I agree with this for consumers, but how would you decide which providers get in? Would you exclude providers who censor sites when ordered to by a court of law or for purposes of compliance with laws passed by democratic governments?

      Good questions, and I don't know what the answers are - but whatever requirements are agreed upon, it is surely better than "just do what the DHCP tags say and hope for the best #yolo". If you happen to like your ISP's policy better, then change the default!

          Easy for you or me to say -- our Twitter bios say both of us live in the US. (And the first thing I did after plugging in my router was set the DNS IPs to Google & OpenDNS.) Folks on better EU ISPs may like their ISP DNS. (Of course, using the same servers w/ DoH would be fine.)

          Right, they might like their ISP and they can choose to use that one. Everyone agrees on that. All I'm saying is, until they've confirmed their ISP is safe, let's use a safe default? They could be using the free wifi at a gas station for all we know.
