I'm sure that line between PR and "forum mod" can get blurred over the years, but that's exactly the OP's point. The YC community, as it has scaled, is no unbiased marketplace, and it has not handling scaling responsibly. Look at the founders who were ousted from bookface, or even some of the non-public discussions there. The OP's Stripe commentary might be over the top, but YC has yet to produce a mature response to any of these friction points.
How could they produce the mature response you’re looking for when the accusations are full of holes. Lyft isn’t a YC company and didn’t use Stripe initially as he claims. The only “Proof” (his words) posted is incorrect: Stripe posted their blog post before he posted his.
He has produced no real evidence for his claims. The evidence he has tried to produce is trivial to check and works against his claims.
How should YC respond to this?
