What is the actual consequence of this "lost privacy"? What would be tangibly different in your life right now if you hadn't "lost" it?
My answer - nothing whatsoever, no harm comes to me at all from some statistical algorithm calculating what ads I might want to see, and in fact I've bought several cool products off Instagram that I didn't know about otherwise. This is a completely illusory harm that has been made up by what is essentially a cabal of professional agitators and propagandists.
