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?
I would add to your list, what if the company with that job offer you applied to asks for your consent to do a background check on you (they do) and then they pay other company that specializes in tracking all your information (these companies exist)?.
