What harm does public data have to you? Couldn’t one just ignore the ads? You can’t see anyone watching you, is public data good for public records? (I’m just curious). I know this sounds weird but is public data good for historical preservation and knowledge increasing the importance of the individual? And does public data lead to better products?
The more there is known about you, the easier you are to be manipulated.
If you read George Orwell‘s 1984 or watch the Cambridge Analytica documentary on Netflix you get an idea.
I started to read 1984 a couple years ago but it is so triggering I had to stop. It really sets your head straight. Might start again soon.
