But privacy violations are closing in on us, chipping away at our walls one inch at a time. Advertising networks are tracking everything we do online. Companies are selling our home addresses, phone numbers, email addresses, and lists of family members.

Apple patented facial recognition software, and they’re not the only ones who have it.
