That Feeling That Email Is Watching You Isn't Paranoia
Imagine a letter arrives in your mailbox. Ordinary envelope, nothing remarkable about it. Except taped inside the flap is a small device: the moment you open the envelope, it reports back to the sender the exact time and your location. Not because you asked for that. Not because you agreed to it. Because they wanted to know, and the technology to find out was cheap enough to include.
We’d call that a crime. Tampering, surveillance, something. Nobody would accept “well, you opened the envelope” as a defense.
