I disagree with each and every one of these ratings and conclusions.
Firstly, the comparison should be "Is the alternative to YC worth it?" For many companies, the alternative is raising nothing and bootstrapping, or raising at significantly lower valuations.
Additionally, I believe founders approach YC the wrong way. YC is not there to coddle you. They are there to give you access to hundreds of exceptional founders, brilliant partners who have seen much more than you, and a fundraising platform.
It is on the founder to adapt their behavior to get the most out of Y Combinator. Unfortunately, many founders are unable to do so, and waste the opportunity.
