DoH is a technical win but a practical regression for anyone who actually runs their own DNS. With classic DNS, you could hand out your resolver via DHCP and transparently control local zones. With DoH, that's gone. You have to configure each client explicitly, because the traffic is wrapped in HTTPS and can't be intercepted.
And the defaults don't help: instead of your ISP seeing your queries, now it's Cloudflare, Google, or whichever big player your browser hardcodes. That's not decentralization, it's centralization under a shinier marketing story.
Encryption is good, censorship resistance is good, but the rollout conveniently shifts power away from users and toward a handful of global DNS silos. For technical folks, it feels less like progress and more like lock-in with extra steps.
