That's basically my point. HN people are wealthy and spend most of their working hours
and free time on the internet. They also vehemently hate ad-supported business models.
Hell, I probably built my entire career off internet searches.
In theory, HN people should have the most to gain from a better search engine, and be the most likely to pay for one. Yet, to your point, the alternatives are free and good enough.
The problem is, what the mob moralistically claims they want on HN (when upvotes/downvotes are a concern), vs. what those same people actually do in the real world on an individual level, are two separate things.
The lesson is, things evolved the way they have on the internet for a reason. It's not some "evil" companies shoving these ad-supported business models down our throats. We have all voted with our eyeballs and our (lack of) dollars, and will continue to do so. We get exactly the products we deserve.
