In the wake of the Zenefits scandal (which is only just beginning) there's going to be a lot of scrutiny on Y Combinator and the entitlement culture (and, hence, the cheating culture) that tends to emerge from an old-boy-network.

They're trying to put a good foot forward and distance themselves from the culture that created Zenefits and (more importantly, in the long term) from the appearance that YC is just a bunch of companies buying each others services at high prices, like artists who'd buy each others paintings at high levels (to bolster each others' reputations) while secretly settling the bill.

I don't fault YC for doing so, and I doubt that they had any official, direct responsibility for the Zenefits fiasco (although I certainly don't buy that Mr. Conrad acted alone.) It's just useful to be able to read between the lines and see what's going on. Y Combinator's PR wing is definitely going to be active as long as Zenefits is in the news.
