It&#x27;s also very much possible to draw the wrong conclusions as you mentioned. So while data may not lie, there certainly are plenty of faulty interpretations.<p>What scares me is the fact the data aggregation is being done with mere promises of &quot;trust us, we won&#x27;t look&quot; . Systems built this way are inherently vulnerable to secondary and tertiary usage. That&#x27;s why I think there is a strong case for end to end encryption so that there is separation but ultimately this is still a problem because there is no way to enforce metadata constraints on data. Someone may design such a system but others will just resort to using something else. Frustrating.
