Most people and I mean upwards of 98% (even the tech savvy ones) don't care much about privacy as much as the HN bubble seems to(or pretends to).
The amount of data collection is truly bad for people living in totalitarian regimes or have sensitive jobs but that's not the majority of friends for most of us. For the rest, the lack of privacy has no negative impact on their life and is unlikely to have in the near future, so there's no reason to change.
Wanting change to benefit all of us is what we try (and fail) with preventing climate warming.
