How secure is secure DNS from spying?

There are certain recently very active spy services.
So my question in which countrys are the dns servers and could their traffic be potentially evadropped?

Is no one here?
Can i safely use the product without having all my traffic send directly to the bad guys?

I guess that no one did answer me does mean that it is not safe to use


could the traffic be evadropped and secure dns be less secure from spying than using ‘normal’ dns?
