I’m not so sure that hyper targeted ads based on a ton of granular data about me is a requisite for modern business not to collapse in on itself.

Advertisers made do just fine for quite a long time only being able to target the sort of people that would probably be consuming a given magazine or TV show. Ok so this is an auto enthusiast magazine, so lets advertise auto parts. This is a parenting magazine so advertise baby stuff. Etc. Same thing can be done online.

They don’t need to have a creepy level of information about us and if they do their business model maybe doesn’t deserve to stay afloat.
