(FWIW, it seems like a clear warning could have been enough from YC (but I don't know how the entire thing is presented beforehand), but your post looks extremely childish and hard to take seriously)
Essentially, the day before he saw a company FooCo having open office hours with Sam Altman and Yuri Sagalo.. Sam and Yuri were talking with FooCo about their business and industry X.
The next day he got a (closed, but easily viewable apparently) office hour with another YC member, along with... A direct competitor to FooCO in industry X. Possibly funded by YC was on the same call.
To the author (and to me) this looks like a nice PR mechanism (with some social pressure once you're up on stage) coupled with a great competitive analysis rolled into one.
I don't think YC liked having the drapes pulled back and having the information asymmetry revealed.
But the real moral of the story is finance guys (and YC are just west coast bankers) look after the finance first.
