I do not understand that. The user can choose to send cookies to DDG even if
DDG is not supposed to use them?
If the user changes anything on https://duckduckgo.com/settings a cookie is
stored, so that the changes are locally saved and can be applied for the
subsequent searches.
I do not have any problem with DDG incrementing a trisquel counter, but as
pointed by andyprough (and he deserves all credit for that) this is not a
matter of trusting people to honor their promise, this is a matter of
understanding what is going where. If something does not need to be sent, why
send it by default? If some innocuous data has to be sent in order to
generate some revenue, why not make it clear, and even better, let the user
choose?
I agree.
