I've always felt like data gathering is kind of like lobbying. It is not directed toward you in person. It is used to shift the way people think and their opinions on topics.

A company / non-profit / movement / whatever lobbying towards a goal might be buying lunches or making seminars and talking about their point with selected group of people who have a say in a topic. Or they might not but they are in the vicinity of the topic or perhaps they are a group that a the company feels like they do not know what the fuck they are talking about and that needs to change.

These are not directed toward you but to a group of people whom you most likely have nothing to do with. This group has power to change something. Whether for good or for bad, that depends who doing the lobbying and for what purpose and how you think about the topic.

Data gathering is similar. This data that is being gathered is not identifiable to you (or it can be but this is not what I am talking about) but it gets clumped together with a buuuuunch of people. This bunch might be people from country x or Christians or people who like Mc Donald's or who are against gun-rights or pro abortion or people whom think that companies should not be pushing climate change responsibility to the consumer. This clump of people are the same bunch that the lobbyists are targeting. But they do not have direct power over a subject, in general. Point being that even if most of the people have no power over a topic, some of them might (they might hold power oma person company deciding whether to do more against climate change). And even if they do not, they will converse about the topic and this will shift the general consensus around a topic.

And this bunch of people can be very accurately targeted. People in their 20-30s, who graduated (or will soon) from a university that are most likely to go work in high-tech companies in or in the government who have people around them (family, friends) that are against gun-rights but still own guns and do hunting? Ezpz. Or perhaps own a car and drive a lot and have relatives far enough that car is a necessity but have shifted their thinking being more against cars? Np.

The problem is that this does not easily be used against you in particular. But it can be used against a group of people that you are a part of. It is used to shift the way we think as a community. It is used to push ads and news articles (or just the topics of articles because glancing it also works) to you, comments in twitter, posts in Facebook, and change the search results that you might see. Kind of like ads as well; ads work really well even though lots (most?) people would say that ads don't make them buy a product and only annoy them. Advertisers aren't dumb, they know exactly what people think and how they function, and ads work.

And again to reiterate, it has nothing to do with you. You are a blip. But you are a part of a larger community and in order to shift that community toward something all of its little bits and pieces need to be moved toward that target. Not all of them need to move toward that target. Just enough.

This got a bit rambly I think but anyhooo it's kinda how I see it.
