Interestingly, perhaps, I see YC's connection to this story as more that it runs the site that broke the story: this one. I suspect pg getting involved is more because he personally likes the AirBnB founders rather than that he sees it as the responsibility of YC.
That is not the relevant number. YC will tend to care about the bad publicity in direct proportion to how much of the stock they own, and they probably own a lot more than 0.01% of AirBnB.
YC had to invest in a lot of startups that didn't get as far as AirBnB to end up owning ~6% of an AirBnB.
This is wrong in far more than 5 ways, but we will start with 5.
1. Your model of "money on the line" doesn't seem to account for diminishing marginal utility (if a billionaire has $1 million at risk, and a millionaire has $1k at risk, the risk is greater for the millionaire even though the percentage risk is equal).
2. Your model doesn't seem to account for relative portfolio size (if a billionaire risks $1 million, and a $10 millionaire also risks $1 million, the risk is greater for the $10 millionaire)
3. Your model doesn't seem to account for the opportunity cost of time (YC seems to like/have time for talking to the press about YC companies, something that many VC firms don't)
4. Your model doesn't seem to account for relative skill (YC seems better at talking to the press than most VC firms)
5. Your model doesn't seem to account for compensation options (if YC doesn't feel that time spent would be positive ROI, AirBnB or the other investors might be able to pay YC to do it)
In short, my coming on HN to read interesting business discussion, only to find thoughts like "Saying that YC should handle this would be like suggesting that Bill Gate's Harvard fraternity should clean up Microsoft's faux pas (That's a bit hyperbolic, but I think you see what I'm getting at.)" is like being invited by a friend to the symphony, and showing up to discover a five year old alternating between playing a xylophone and eating wood glue (That's a bit hyperbolic, but I think you see what I'm getting at).
I just think that articles like this one[1] have put them in a bind with respect to this story.
I'm left with the impression that you think YC is in a bind here because you want them to be in a bind here. It sure is a lot more fun to talk about, isn't it?
If you're on record talking about someone's positive qualities, and they make a mistake, or even are accused of making a mistake, that puts others in a position of expecting you to have a position on it. But they can't really take a public position on it beyond what pg's already said on the matter, and we see what good that did. This is the bind I am talking about.
I don't want them to be in a bind. I have no feelings one way or the other about the matter, really, I am just attempting to offer my point of view on why people are clamoring for YC to be more vocal about this topic.
The logic that involves YC in the Airbnb drama is juvenile. Sorry to be so blunt about it; I know nobody likes being called names.
I don't think it's right, and maybe I have just been in DC too long, but this is how this sort of thing works in the media. I never said they owe an explanation to anyone or anything like that, but people are _clearly_ expecting one. Something set that expectation.
Maybe this makes me juvenile, that's fine.
