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
