I guess the question here is what you mean by "privacy." It seems to me that privacy goes beyond merely avoiding the risk of fingerprinting, or individualized identification. Collective identification is also a privacy problem: if I get advertisements targeted at people with similar political beliefs to mine because I've labelled as a member of a cohort that has visited a cluster of X-leaning news sites, that seems objectionable independent of whether the owner of some website can also distinguish me as an individual from every other member of the cohort.
