I also stay indoors so that public security cameras can't see me :) I don't have a bank account or Amazon account :) I live curled up in my basement shaking with terror at the prospect of my privacy being violated :)
okay, this is the same attitude I am met with when I say this statement.
There seems to be a either full optimistic response or a pessimistic response. I am not saying abandon smartphones all ye who want privacy, I am saying that for those who aren't addicted to smartphones and want privacy they use non smart phones.
In a world where a private company owns public security cameras, yeah you should stay indoors because they track you every hour of every day, they built a machine to spy on you and they'll devour you.
Doing something is subject to realizing if the +ve aspects outweigh the -ve aspects, in a world where Google owns android/chrome/search/gmail/nest/adsense {insert million products here}
In this digital world these companies know more about us from analytic than we ourselves know, but that doesn't mean being pessimistic to anyone who suggests a particular use case for maintaining privacy.
