It’s worth remembering that when people give that advice on HN, it’s usually in a business-to-business context. Business-to-consumer sales are a different thing entirely, with different motivations and often a different purchasing process. Consumer purchasing behaviour can be highly price-sensitive (and affected by numerous other factors as well as price) so for software or a service with low marginal costs, offering lower prices with greater numbers of sales can easily work out better than higher prices but fewer sales.
