I agree. I think this is one of the key reasons HN succeeds as it does: the narrow, delimited incentives on the part of YC. All of the writing and discussion that exists on HN, which isn't a YC ad, is a "halo" to attract and retain readers to this forum (and see the YC logos and YC ads). That's their primary incentive: attract users, attract a specific culture of users. It's an incentive aligned with quality and pleasantness for us. The daily forum experience isn't the revenue source; to monetize that, YC would risk losing more (on their YC-halo boosting side) than they could expect to gain (from McDonald's ads, or whatever). This is the diametric opposite of how most social media platforms think about users, and their business models around them. The Reddit IPO is a case study: they've willingly chased away countless millions of users with an abrasive, horrible forum experience, because they calculate they can extract more revenue from those that remain. Where HN is a "narrow, tall" revenue source surrounded by free stuff, Reddit is "wide and short": everyone and everything is the product.
