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?
Thing is people who have bad things in mind are always more likely to use their own codes. You dont need an encrypted messenger to send encrypted messages. It’s a boy.
But normal people who think that they have nothing to fear and therefore nothing to hide won’t take that efforts upon them. They will live their lifes and one day they could be targeted by a government that wants to eradicate them. Using the data their predecessors gathered.
