      Yeah, but it seems like a better default than trusting whatever happens to be in the dhcp options 🤷🏻‍♂️. Maybe the default should be a RR of providers that meet availability standards (like CT logs do), I dunno.

      That seems like a pretty cynical interpretation dude. It's just the default, I think when users go to McDonald's free WiFi, they're usually not explicitly stating they wanted to trust the McDonald's DHCP option tags. 🤷🏻‍♂️

      Ahh, the tweet you were quoting said "DNS privacy is a huge issue", it sounds like you disagree with that, and think it's not an issue at all - You want browsers to just do what the network admins indicate?

          I've heard the argument, network admins argue it's a source of visibility into what their users are doing, and this is "going dark". If they have admin on the endpoints they can disable it - but I think it shouldn't be the default, because of the Starbucks Wifi scenario.

          On a corporate network then yes!

          If corporate network means you have admin on all the endpoints, I agree with you, and that is already the case! You have permission to set the DNS options to whatever you choose. If you don't have admin on the endpoints, then I strongly disagree with you 😛
