Not too sure about that, most of the younger generation want privacy via messenger services, giving an email address to obtain. Some move from for example What's App to Telegram believing one to be more secure than the other for sending messages privately.
On the other hand some people will post breakfast, lunch and supper out to the world forgetting to switch off Geo-location, which is extremely dangerous in our world today.
Blockchain technology is being promoted as private and secure, again somewhere along the line you divulge your email/phone credentials, an IP address is traceable, just how much privacy do we have in this world today, is a worrying reality.
Listening into your life and what you do is big business! My respect goes to people like Edward Snowden and other whistle blowers against the powers that be.
