So you walked into a French restaurant in the 16th century every week and there was an artist sitting outside and the proprietor took notes on every conversation you had and the artist made portraits from everything you were wearing every week and they all sold it down the river.

The shopkeeper knows your face and every baguette you ever purchased three times a week. Every miller within 300 km knows about that time you complained about the stale bread they sold you.

What is the big diff and nobody needs high tech to compromise your privacy
