There are always microphones, everywhere, all the time.
I remember when I was a toddler and they taught me that Santa's elves and God's angels where spying me to make sure I was good. They later told me it was a lie. It became true soon enough.
Fighting for privacy is impossible. We should fight instead for transparency, that means, spying those with power. And we should fight for equal rights, that means, making it hard for people to hurt you with the private knowledge they have from you.
How sad.
