My hypothesis is the adage "out of sight, out of mind". Is not the same having someone physically following you everywhere in a surveillance van, looking inside your home, when you buy groceries the cashier hands a copy of your receipt to the surveillance guy, etc. Since all that happens "hidden" away through the many services, apps, store cards, credit cards, etc. Although not all are too 'hidden away' as you can read it on their TOS and privacy terms or overwhelmingly obvious like in places like casinos with all the cameras but people cant be bothered reading TOS or got normalized to see all the cameras. We also often overestimate ourselves (human beings) thinking we have a level of intelligence and rational capacity but in reality we are more emotional and prioritize bias over rationality.

I think the recent allegations (whether true or not) that period tracking apps in USA (and other counties where abortion is illegal) might make users' data available to goverments could make people reconsider.

Do you mean Lumpenproletariat?
