Why is online privacy so important? (self.asklemmy)

Firstly, I'm not against privacy or anything, just ignorant. I do try to stay pretty private despite that.

I wanted to know what type of info (Corporations? Governments? Websites??) Typically get from you and how they use it and how that affects me.

There was a jogging app known as Strava that posted an image on their Twitter that was a heatmap of all the jogging activities of all of their users. Their idea was just to show how popular their app was by showing the entire world lit up. Twitter users were able to locate secret US military bases on that data alone. Turns out nobody jogs in circles in the middle of the desert except GIs.

Recently a group of Harvard students did a demo where they used Meta's camera glasses and a chain of commercial programs and products to find out people's names, address, workplaces, and family based only on their facial data.

These are just two examples off the top of my head. Essentially, the more data someone can accumulate, the more info can be analyzed from it. With things like AI tools, that analysis is incredibly fast even with huge datasets.
