Are you being serious? Valid criticism isn't the same as hating on the playa', to use your apparent vernacular. Many would consider criticism to be a considerate act and an opportunity to learn from one's mistakes. Just because you're not one of those people it doesn't mean everyone else is being mean, not to mention that many of the comments here are about YC itself rather than the article's author.
Also, YC isn't just about getting "sweet sweet" money, it's also about commitment, many times to the point of collapse due to overwork. This may be a worthwhile tradeoff for you, but it doesn't mean that whoever is critical towards the way YC works is actually broke and bitter. I'm actually quite confident that HN has a sizable population of mature, fulfilled and well-off readers who have better things to do than to pick on the unsuccessful.
Not to mention that many young people are in way over their heads when getting into this, and lack the experience necessary to come out on top. Some pull through, but in this case it was clear more or less from the start that it wasn't the case.
No one's envious nor blaming them for being too young or with half-baked ideas, it's understood that young people are naturally less adept at things. My impression is that they're rather criticizing YC for using inexperienced youngsters as fodder for investors, for just dumping responsibility on them, then leaving them to do the sweating and feel like hell for getting in without a clear plan.
Before being judgemental and assuming the worst about people, maybe you should stop and evaluate your own negativistic projections.
