Here a conformant DNT product has always a header.

Here a conformant DNT product doesn't send a header.

Contradiction. no?
I guess what you want to say is that 
1. a proxy can't add a DNT header if none is already present in the headers without user consent. (this creates an issue for proxy)
2. a product can't remove or change the header value without user consents.
