What the article misses a bit, in my opinion, is that protection of privacy is also a protection of collective freedom - very similar to freedom of speech, or protection of one's living space from search without a warrant. Like "Saying I don't need privacy because I have nothing to hide is like saying we don't need free speech, because I have nothing to say".
This is an abstract concept, but the case of Cambridge Analytica and its interference in the UK's Brexit referendum is a great example about the enormous real consequences. (More on this in Carole Cadwalladrs "The Great British Brexit Robbery", which was for some time "de-published" (ahem) from The Guardian but you can find it in the web.)
