“Concerns over DNS Blocking” by Vinton Cerf
French people really like to protest, so maybe we can teach them all to set up their own DNS resolvers with Raspberry Pis?
It would be a really, really difficult law to police if individuals were all managing their own DNS resolvers.

I’m not sure what this means. Almost all traffic data identifies someone, whether it’s the customer or their destination. I’m assuming they just don’t care about the latter, but it’s still identifying information.
I swear there was just a case of a German judge doing exactly what they’re worried about in the article, though, telling a DNS resolver that they had to censor a site from the whole internet to comply with their law.

Anybody who wants to can get around DNS blocks. Sure it’ll stop Aunt Sally, but anyone who cares will get around it. It’s a really dumb way of doing things.
It’s trivial for me to detect and block dns over https with modern firewalls.
How? I don’t see what could find dns-over-https in the middle of other https traffic?
there is a lot more to modern firewall app detection than ports. My Palo Alto has a specific category to detect and block dns over https.
Even Palo Alto notes that they can only effectively block DoH if you’re MITMing all https traffic already (e.g. using a root certificate on corporate-managed devices). If not able to MITM the connection, it will still try to block popular DoH providers, though.
