The link you shared - Those simply are submitted titles to HN, not necessarily the discussions around them. If you read most of them, it's usually pro-surveillance and the argument is almost always along the lines of "I've got nothing to hide"
I wonder how much of the people who comment in defense of these kinds of things work for Flock/Palantir or something surveillance related. Often when there's discussion of ads you also have people who chime in with "I think personalized ads are very useful" comments. And I'm intensely suspicious of these since seeing someone get called out once.
Exactly, I appreciate the comment and I think this is exactly the kind of critical question we must ask when someone tries to normalize surveillance.
