Good questions. I honestly can't come to a guess. On one hand, making the data anonymous would explain the interest in crazy fingerprinting methods and why companies that do that aren't very well known. On the other hand, I have no strong evidence to support the idea that an ISP would anonymize data given their history of activity in the name of profits and in spite of customer satisfaction.
