"When I use my discount card at the grocery store? Every purchase? That's a dataset for sale."
He's just using that as a general example, right ? He does not, himself, as a data privacy expert and knowledgeable user of networks actually use a grocery discount card, right ?
Further, the more general set of examples that make up his narrative rely, to some degree, on using a mobile device that is connected to, or even registered in, his actual, real name.
He doesn't do that, right ? Is anyone here doing that ?
