I don't think YCombinator is supposed to be a megacorp with that much control over the startups it's founded, and I don't think that a few slipups like what happend to OP warrant adding all that red tape in the long run
I was not thinking in terms of startups losing control but rather startups sharing and getting YC’s insights into candidates. Plus startups not being bogged down with terrible candidates if YC were to filter it for them. It’s Efficiency in scale all around honestly.
