PiHole with upstream dns-over-tls or dns-over-https.

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.
- Well our government likes doing dumb things. That is kind of their platform lately.
  
  As as US idiot, it feels good to have been right about how much of a corpo scumfuck Macron is.
- 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?
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.
- Sure we do, but you cannot expect everyone to simply run their own DNS and call it a day.
  
  The vast majority of people don't even know that DNS even exist, let alone that your ISP can monitor/alter your traffic through it.
  
  I'll admit, it's a much less "exciting" way to protest than flipping cop cars and starting fires.
I'm out of the loop, what is France trying to do with regard to DNS?
- Government-mandated DNS blocklists.
  
  Thanks for the info. That seems quite heavy handed.
As much as I dislike wasteful cryptography, this seems like an really good use case for cryptographically signed and owned names. Kind of like ENS domain names.

That way no single third party you can remove you from the internet effectively
demand non-identifying traffic data from electronic communications operators on-demand

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.
