I think it's more that people outside of HN don't really care about their privacy if it's not visibly being violated. From there it's cheapest and biggest wins
I talk to a lot of them about privacy, and nearly all of them do care. They just have no idea what's happening, and after I tell them, they have no idea how to stop it and give up. Happens every time.
I have a friend who "just doesn't care that much about it"... to the amount that it is straining my ability to continue the friendship (unbeknownst to him). (He's not a techy person, and is in(to?) Apple's walled-off gardens.)
And, because of people like him, anti-privacy micro steps are continuously made, and Overton windows slowly but continually shifts... until one moment when he/they start to care, but then it's too late. And then they're usually greatly surprised and astonished that "that's allowed?!".
Yeah, it is, buddy, it is. Because you "just didn't care that much". Now you have to live with consequences that the rest of who "did care" have lived (and fought) with since the [metaphorical] beginning.
