      If you’re freaked out that your browser turned something called “DNS over HTTPS” on, you’re being bamboozled. DoH is a good thing.

      You say “DNS over HTTPS” rather than “all your web browsing history will be sent to Cloudflare”. These are separate things, and Mozilla is doing both for all US users. Cloudflare has a history of sharing personal data with hate groups.https://www.google.com/amp/s/www.propublica.org/article/how-cloudflare-helps-serve-up-hate-on-the-web/amp …

      Cloudflare are problematic. There's no reason to think they're not law-abiding though, and Mozilla have negotiated an enforceable policy. IIUC, there are plans to add more providers to the pool in future, but right now this is *still* a more sensible default than "Trust DHCP".

          Until we have a wide adoption of encrypted SNI, you can't hide from the ISP anyway, making DoH a net loss for privacy.

          There’s an underpants gnome thing happening in the middle of that analysis.

          Assuming that Cloudflare are in fact forbidden from turning this data into money (or even collecting it?), what do they gain from running this DoH service? What's the business model here?

          Project Zero doesn't make any money either, I imagine it's the same reason, making the internet safer and more trustworthy is good business. 🤷‍♂️

          We have already added NextDNS (in Nightly...would have to check release).

          I tried Cloudflare dns for a week or so. Found many things that I use regularly wouldn't work anymore like they were blocked. There theres the "we have anonymous dns but we collect data and share it with a partner" bullshit that makes me wonder what they're really up to.
