They should care because they've created an excellent community and a wonderful forum for thoughtful discussion, not many of which exist on the internet. It's something to embrace and be proud of. It's not perfect but it puts every other fairly large public internet forum I've seen to shame. Not everything has to be done for economic gain. If you want to pretend it's all a ruse to make more money then you are free to consider having such a robust discussion forum to be good PR for Y Combinator; it garners an enormous amount of goodwill and respect in the tech community. And they do care about earnest thoughtful balanced conversation. There are plenty of posts critical of YC companies or PG or you name it that are not censored. Mods interact with the community regularly to enforce standards and curate post quality.
