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?
These days, with “big data” analysis being possible on such a large scale, it’s possible to gauge the position of the general population, or of subgroup of such with ease. This makes it easy to divide and conquer, to manufacture consent, for whatever those who have access to said analysis desire.
I always tell people, it’s not about your data, it’s about our data.
