Happened upon this thread a little late, but I see a lot of confusion here. There are various types of privacy being all lumped into one here, and they're not all equal.
For example, security is being treated as privacy, when we talk about Aadhaar or passwords stored as plain text, etc. That's not a privacy issue that's a pure security issue. People can do bad things with that data. Like create fake bank accounts in your name and endanger your freedom (you going to jail) or if you use the same passwords everywhere, it can endanger your assets (such as bank accounts), or even your email address, etc. This is security, not privacy.
Next, is the personal space privacy being discussed, which is parents not letting you be alone, or hostels not giving you single rooms, etc. That's a valid problem in every crowded country, and even a problem with minors in developed and sparsely populated countries as well. It's more societal than anything else, and with houses getting smaller and smaller because of congestion (all over the globe) this is a problem that will only get worse. If you think you have it bad here in India, think about the Japanese city dwellers who have it far worse than most of us when it comes to lack of personal privacy. There is a psychological effect that needs to be discussed as well, which may explain the more violent tendencies of some people these days, which may very well be linked to a lack of space in general, or the lack of privacy.
Lastly, we have online / offline anonymity, which is debated as to whether it's even a valid privacy whinge. more and more internet services want to know who you are, and aren't interested in catering to anonymous people. Places like this forum are some of the last spaces left online (decent places, I mean) where people can still interact with others without revealing who they actually are in the "real world". Most of us don't use that feature or ability, admittedly, but it still exists nonetheless.
Aadhaar raised the question of whether a citizen deserves the right to be anonymous, and choose what data they want to share with their governments or corporations. Now, one can claim that in order to receive government benefits, one needs to be identified (still debatable whether biometrics is needed), and that would be true, but some believe that we as people have a right to exist without giving our details to everyone.
Of course that last one is getting more and more impossible to do, anywhere in the world. No one employs people without background checks, and checks of identity, societal standing and even social media stalking to assess an employee's stance on important subjects. For example, in the west, no one wants to hire a white supremacist, or a Nazi, and while we might argue that it is against free speech, or something like that, one also cannot argue against the fact that a company needs to be able to make a profit, and fire or not hire individuals who are detrimental to that goal.
In essence, the days of anonymity online or offline for most popular things is at an end. Yes, this forum is still one of the few remaining places that we have to be able to be anonymous, but such places are few and far between now.
CCTVs, Facebook and the likes, and even ad networks, etc, are all tracking you and know who you are. For the most part, it's only because they want to try and sell you some crap, so it's not really evil, but there will always be a few that will use your data against you in ever increasing evil ways, without you even knowing it. Influencing voting and elections, shady politics in general, fear mongering, etc, are all on the rise thanks to social media, and that's not going anywhere, sadly. Either way, wishing for anonymity is just wishful thinking now, so get used to spending your life under the glare of the spotlight of the world, and being judged for every little thing. It's the sad future of our species, for better or worse...
