My own two cents: it's a very unfortunate blog post.

1) As mentioned few times here, "cultural variations" can not be handled as such, unless you have a special training on this -which I don't read so -.

2) It's totally a back pusher on applicants, if someone says "I see through you, and tell if you're evil", I say, "no thanks, have a nice day with your corporate culture". Indeed, I'm not considering to apply YC with this attitude. (Therefore, I'm not good, possibly caught by JL-radar)

3) Regarding 2, I think YC became too picky, so they're starting to sound these -nonsense- ideas to cutoff pouring applications.

I miss PG's guidance.
