YC competitors will fail if they don't have honest soul to help others to grow. Also YC model looks easy from outside but if you try to know the nity-gritty of their business model then you will realize that its a hard work and the passion behind it has to be genuine otherwise there would have been hundreds of clones all over world. I see YC as a social entrepreneurship than just a money making machine and hence if Pg can share something that can help other entrepreneurs and countries then it would be like an adding jewel to his legacy crown.
"Benevolent" != "do all the work for your competitors". Besides, if you're not smart enough to figure out how to improve on the YC model on your own, why should entrepreneurs come to you for advice?
