On HN you're mostly talking to a niche of people who are both a) consumers and b) spend all day in code, not end-user tools.
Consumers, as a rule of thumb, mostly consume, and irrationally value their time at $0. They don't build things like companies do, so don't perceive any monetary value in doing something more efficiently via software like a company would. They'll waste hours of their life to save $5, because what would they be doing otherwise? Scrolling Instagram or watching YouTube, so who cares.
Coders, as a rule of thumb, mostly code, and irrationally value the code of other people at $0. In the back of their mind they always believe they can "code up a better replacement in a weekend." Even though this is 99.99% of the time not true.
So the intersection of these two groups could be the worst software market on earth.
