You’re not thinking on a big enough scale. No big tech company cares about “your” data. They care about everyone’s data in aggregate as much as they can get from every location at every granularity. Even thinking of a tech company as collecting all of “your” data to create an ad profile “for you” is rather inaccurate. They’re collecting everyone’s data to create an ad profile for everybody, tailored to what makes the most money in aggregate across all ad slots. When you think of it like this you’ll stop asking questions like “what would they do with this piece of data?” Because the answer is always that it is a drop in a giant ocean of machine learning data.
