Also interesting that they goal doesn't include helping startups be more of a good thing.
To be clear, I generally believe that YC will help there be more good startups, but it is kind of weird phrasing.
"We must remember that we’re investors, not bosses. We can advise and persuade, but not command."
As I understand it, YC is pretty hands off. It's mostly an (usually amazing) advisor you come to with questions when you have them, plus alumni network, plus dinners/demo day. I don't think they can really make people be good instead of bad.
I think if anything, they simply won't fund people that they believe will not do good.
There have been some pretty visible counter-examples to that, fortunately not in the last two batches.
