Amazon marketing broke a fundamental rule about consumer tech: Don't remind users about how much Big Tech knows about you.

Your various devices track everywhere you go, who you communicate with, what you search for, what you buy, what audio you listen to, what videos you watch, what games you play, who your family is, all your pictures and video you take, who comes and goes from your house, when you sleep, your health data, and much more.

And as a fundamental part of Big Tech's business they accumulate, aggregate and analyze all that information in various ways to increase profits. They don't keep this a secret, but wisely they normally don't brag about it to the general public.

Consumers have shown that are totally willing to give up privacy for convenience. Just don't remind them of it.
