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?
Honestly, sometimes my best answer is “none of your business”. Its none of Google’s business what my hobbies are. The fact that there’s no “harm” in it is irrelevant. I want to be left alone, I should be able to without an advanced knowledge of cyber security.
