Yes, although as the article says, gmail was the exception rather than the rule in that most other products did not use customer documents and data to personalize ads. In any case, that was three years ago, and it hardly seems likely that Google will go back to that practice given the increasingly sensitive views of the public toward the use of customer data. It is not my claim that Google would never have used Fitbit data in this way if it had acquired them in the past, only that it seems unlikely that they will on a forward-looking basis.
