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?
“Can’t you just ignore the ads?” Not if they specifically, psychologically, using the most advanced technology, tailored and made specifically so you personally can’t ignore them, using the data they gathered. And then you just have to hope that it’s an ad making you buy shit you don’t need, and not a psyop compaign made for you to change religion, worldview, voting decisions.
