      Bert Hubert  🇪🇺 Retweeted Boing Boing

      This letter from the US service provider industry is quite something. It talks about "data competition" which implies people's data are a legit thing to sell. They also note that encrypting DNS would harm the advertising business. This is why we do not trust the US industry.https://twitter.com/BoingBoing/status/1181206454281396224 …

      America’s rotten ISPs object to encrypted DNS, argue that losing the ability to spy on your traffic puts them at a competitive disadvantage https://boingboing.net/2019/10/07/brandeiswashing.html …

      This is a confusing tweet Bert, aren't you on the side of the ISPs?

      So you can only be against DoH or for it?

      Replying to @AkiTuomi @PowerDNS_Bert

      The core point of contention is whether ISPs get the queries by default. The benefit of DoH is that we can control who gets to see them. I understand you're indifferent to DoH if the ISP still gets the queries. I'm sure you already understand this, I don't know why you asked?

      "Whether the ISPs get the queries" is not even my main complaint, it's "the browser is willfully bypassing system settings" and "over HTTP". DNS over TLS exists, quad-X resolvers (with DoT) exist. DoH is just silly.

      The problem is you are one of the lucky few who only use trustworthy networks. Many people do not have that luxury, like the customers of the ISPs in the article above. Is it your opinion that it just sucks to be them, and we should do nothing?

      So denying people control over DNS and whisking off queries to a jurisdiction with weaker privacy legislation is beneficial if their network is untrustworthy? I see.

      Yes, if your network is untrustworthy "whisking off" the queries to a trustworthy network seems like a good idea to me. Nobody is denying anyone control, what are you basing that on?

          Replying to @taviso @Cron2Gert and

          For one thing, as I understand it, centralised DoH will let browsers and appliances circumvent my own (and any state-mandated) DNS-based blocklists. Furthermore, what I consider trustworthy is for me to decide. Information Ssecurity is about control.

          Absolutely not, this is just about choosing safe defaults. Nobody is suggesting you shouldn't be allowed to choose who is trustworthy. If you're lucky enough to only ever use trustworthy networks, great! Many people are not that lucky, and we should help them, right?
