Well intentioned probably. Full of suck though. Let's face it, if Y Combinator can't fund a few scholarships for whatever school it wants to, it isn't the most successful incubator in the world, or whatever it is. It can and it should it it wants to. Drawing attention to it like this seems remarkably gauche.
This seems to implicitly support the 'poor' in a rather patronising way. Rich person pays for kid to come to dinner. Poor person gets gift of education.
Wonder who would bid if it was rich person gets to pay for poor person's kid to go to dinner and rich kid gets 0?
