Centrality of DNS article and DoH/DoT to root resolvers

I could see how they would filter or block the packets, but I’m not sure how they could profile you unless they can read what DNS you’re looking up. Part of the reason to capture your DNS is that it’s much less resource intensive than watching where you actually go.

I don’t think most ISPs care where you go, except to sell your data. If it costs them more to collect your data than it does to sell it, they wont do it. ATM, I suspect saving that information by means more complicated than DNS logging (or some sort of cookie) might be too costly. But that’s just a guess on my part.

I believe this only applies to default behavior of browsers and wouldn’t likely effect ones own resolver infrastructure like I’m describing here.

If someone is really interested in where I go and what I do online, there’s not much that can be done to stop that. Also, if they’re really that interested, I likely have more problems than just trying to keep my activity from 3rd party advertisers.
