I read a bit about using a different DNS for Privacy and I think the best one should be quad9? Or is there anything better except self hosting a DNS?

  • As I said:

    as it’ll make fingerprinting also much easier.

    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.
