I wouldn't say it's either of the two, but more that the Venn diagram of people willing to pay for search and HN users looks like a Mastercard logo.
There isn’t really anything secret to HN. It’s not unbiased, but it’s easy to see which posts are “sponsored” as in the case of job postings. Obviously Kagi will rank well since it’s very popular with HN, but any “startup” tech company which has new features will typically rank high here.
AFAIK HN does not track link clicks.
