There is a very large industry focused on "re-associating" so-called anonymized information back to PII. Store visits are very easy to re-associate, and ad targeting can be used to de-anonymize people as well. It is virtually impossible to certify that any given disclosure, no matter how grouped, anonymized, fuzzed, etc. is incapable of being re-associated given other data and time. I also do not subscribe to the rather expedient definition that your privacy hasn't been violated as long as no human has seen the data. That's an unsupportable claim. As long as my privacy is only a millisecond away from anyone's view on whim, mistake, or trivial disclosure, or some automated system has made some decision that affects me based on my private data I have been violated.
