In this case though, I'd say you're simply trading one injustice for another.
You go from the ephemeral experience of having a few underpaid lackeys mistrust you, to having an eternal database of everything you buy owned by a third party.
Then again, it's getting pretty ridiculous everywhere. The local supermarkets around me - they've gradually stripped real checkout operators away and replaced them with self service booths that each have LCD's beaming a picture of my own face at myself whilst I shop, with a scary "you're being watched!" banner across the bottom.
It really bothers me that everyday 'essential' things seem to be full of pain points like this for no discernible reason. We have private companies launching rockets, supercomputers in our pockets, and so on and so forth, and yet the "human experience" seems to be constantly degrading. What can we do about this?
