The world in the 1900s:
Librarians: "It is unthinkable that we would ever share a patron's borrowing history!"
Post office employees: "Letters are private, only those commie countries open the mail their citizens send!"
Police officers: "A search warrant from a Judge or probable cause is required before we can search a premises or tap a single, specific phone line!"
The census: "Do you agree to share the full details of your record after 99 years have elapsed?"
The world in the 2000s:
FAANGs: "We know everything about you. Where you go. What you buy. What you read. What you say and to whom. What specific type of taboo pornography you prefer. We'll happily share it with used car salesmen and the hucksters that sell WiFi radiation blockers and healing magnets. Also: Cambridge Analytica, the government, foreign governments, and anyone who asks and can pony up the cash, really. Shh now, I have a quarterly earnings report to finish."
Device manufacturers: "We'll rifle through your photos on a weekly basis, just to see if you've got some banned propaganda. Did I say propaganda? I meant child porn, that's harder to argue with. The algorithm is the same though, and just how the Australian government put uncomfortable information leaks onto the banned CP list, so will your government. No, you can't check the list! You'll have to just trust us."
Search engines: "Tiananmen Square is located in Beijing China. Here's a cute tourist photo. No further information available."
Online Maps: "Tibet (China). Soon: Taiwan (China)."
Media distributors: "We'll go into your home, rifle through your albums, and take the ones we've stopped selling. Oh, not physically of course. No-no-no-no, nothing so barbaric! We'll simply remotely instruct your device to delete anything we no longer want you to watch or listen to. Even if you bought it from somewhere else and uploaded it yourself. It matches a hash, you see? It's got to go!"
Governments: "Scan a barcode so that we can keep a record of your every movement, for public health reasons. Sure, Google and Apple developed a secure, privacy-preserving method to track exposures. We prefer to use our method instead. Did we forget to mention the data retention period? Don't worry about that. Just assume... indefinite."
