People will care about privacy once the lack of it starts affecting them negatively. It's only natural that people aren't worried when they find out data collection has been going on for years or decades, and yet all their dirty secrets have not been used against them.
Most people have bigger worries in their life than who knows what porn they look at. Like putting food on the table, and worrying about how they are gonna pay their medical bills, or wondering if they are gonna get shot by some piggly wiggly at a traffic stop.
I'm not gonna pass judgement on anyone for having bigger fish to fry in the short term.
