My take on DoH is that it will end up being used in a user-hostile to prevent DNS-based ad/tracker blocking solutions like pihole. With DNS over 53/UDP, DNS based ad-blocking solutions are a trivial firewall rule that can be made even on consumer routers.

With DNS over TLS, it's only a matter of time until adtech vendors and other privacy-invading beacons are using DoH/DoT to prevent users from inspecting & blocking these beacons through certificate pinning + traffic obfuscation.

Fundamentally, I believe that users should be able but not required to control traffic that enters and leaves their devices. This should be a fundamental right every person with a connected device should be allowed to excercise.

Corporate interests that increasingly have the loudest voice in these discussions don't seem to hold that view, and the long term prospects of internet users' safety and autonomy are increasingly worrying me


To be clear: DNS over HTTPS allows privacy violating libraries to side-step the host APIs for domain resolution and implement it themselves, with their own servers. Users using DoH to escape censorship regimes or ISP nuttery is something we *should* solve for, but not at the cost of user agency.

@rrix Privacy-violating libraries could already do that, though, with or without standardization of the protocol. If you're running untrusted code with unlimited network access, you're already in a pretty bad spot.

@rrix Anyone can already do that. The only new thing is a standardised protocol.

You would have the exact same result with a browser embedding libunbound to query quad1 or #quad8 over standard DNS.

Having a browser embedding libunbound was advised by the DNS community to have in-browser support for #DNSSEC and #DANE.

The #DNS community seems incapable of intellectual honesty.

@rrix you don't need DNS to side-step the host DNS API. Any technology that can transmit data can send an IP address. DNS over HTTPS isn't opening up any new routes for privacy violations.
