Unfortunately, very few things are in life are actually "fair". "Fair" is also very relative term. The definition of “fair” means one thing to you, one thing to Y-Combinator and something very different to an applicant who got an interview. There are several hundred people across the world right now who had the wind blown out of their sails like you. While I do not personally know anyone at Y-Combinator, from everything I have read, I imagine this is the best system that they have at the moment and are continually refining it. That being said, like anything man-made, it is not perfect and great entrepreneurs will always fall through the cracks. Prove them wrong and be one of those that fell through the cracks.
