A world where data tracking people&#x27;s behaviour is useful to those wanting to sell them products.  Is it really all that speculative to suggest that an apple algorithm (or google) might correlate persons who suddenly take a few extra minutes shaving with persons who in the next week will buy some shaving products?<p>Apple is a supporter of individual privacy, not group privacy.  They have and use lots of behavioural data, anonymized and sorted, but data nevertheless.
