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.
In addition to everythong everyone has said, one major thing that people often don’t think about privacy is how it relates to enshittification.
Modern software services try to optimize everything to make as much money as possible. Everything is a/b tested, and whatever increases some arbitrary metric is what gets released.
They do this by tracking a ton of metrics about how you interact with everything. I know where I work we collect data about every time you click on anything, how long you hover over buttons, etc.
