As I said:
Fingerprinting is a technique where they look at everything they can grab from received requests and try to use that info to identify people. The things you block (like ads and trackers), the used DNS, your user agent, your IP, etc. It's all used to try to identify you. The more you blend in with others, the harder to identify you are. The more custom stuff you have, the easier to identify you are.
If fingerprinting or not having to trust third parties is more important depends on your threat model. But it's important to know the risks of a trust-no-one do-it-yourself approach when making the decision.
Well, my question was specifically about DNS. I don't think that the sites or services you use have any way to know what DNS are you using.
ISP can capture DNS traffic, but this is where threat model comes into play... Like if you are concerned about some entity to collect you profile based on data from ISP which includes both your DNS queries and your IP
Well, you're right. I was mixing a few things up in my head. My bad. Altrough I did find a few interesting ways that can be used by websites to find client side DNS, it isn't exactly the norm or likely to hit you with custom setups.
I retract my point on DNS, but the general notion that do-it-yourself isn't always better stays. Al be it off-topic here now.
Interesting, can you share any links regarding finding client DNS?
There are quite some results if you search online, but here's one with some specific info: https://security.stackexchange.com/questions/129917/how-does-a-website-know-the-dns-server-a-client-uses
