Afterwords we had time for open questions, and I joined the line. When it became my turn, I asked the owner about whether he had any ethical or moral qualms about what he was doing and he just laughed. He gathers data from hidden interactions with client websites (fashion brands, for this demo) to quite literally 'follow the customer around' and 'influence their purchasing decisions'. He was quite proud of just how deep into his shoppers' lives his product was integrated.
When I looked around the room during the height of this exchange, most everyone seemed indifferent and only a few seemed to acknowledge or validate my arguments. It was a supremely disappointing and depressing experience.
