Do you need your privacy?
Yes. So do you.
Kind of a Borg mindset. If we all know everything there is to know about each other wouldn't we collectively be able to make the best choices?
No.
What do you need your privacy for? What do you need to keep secret from the rest of the world?
It's not necessarily about keeping secrets. It's also about things simply not being anyone's business. Like what I earn, who I'm dating, what I like in the bedroom, what kind of food I like, what my favorite restaurant is, etc etc etc.
And why do we need the right not disclose every inch of our lives in public? For protection and safety. To prevent abuse of such data. In a very very broad sense.
Take facebook. As you know, a LOT of people are literally throwing up their entire lives to facebook. They do this in two ways. First, by almost exclusively using facebook platforms for communication (facebook itself, instagram, whatsapp). Next, by surfing on the internet or using apps on all kinds of devices while facebook cookies track everything - including your location if you didn't explicitly tell your phone to turn that off.
On these people, facebook has a GIGANTIC psychological profile the accuracy of which is nothing short of scary. As several studies, as well as the case of Cambridge Analytics, have shown, it is practically trivial to use this data to literally manipulate people into doing certain things. AI engines can literally predict how you'll respond to certain things. Combine that with advertising and they can literally manipulate you into buying things you otherwise wouldn't have bought. It's an incredible abuse of human psychological weaknesses and the power of suggestion.
And the only reason this is possible, is because those people have given up on their privacy, by throwing up all their lives unto a public platform.
IP is a revenue source. Obviously Genius sees this. Google say they care about your privacy but I think this is more PR than reality.
Did you expect Google,
which literally makes money by collecting your private data - the more data, the more money they can ask for ads, to say that they don't care about your private data?
How can we, the collective we, make the best choices for you unless we know everything about you?
Who decides what makes a choice "best"?
In a free society, I get to make choices myself, for myself.
