We didn't notice that we copied your codebase, changed the name then pretended to have built it in four days?
Good grief.
Oh, and now they have their own rendition of the "Aviator" game often advertised by unregulated Eastern-European online casinos: https://members.withyotta.com/moonshot/. You can't make this shit up!
I wrote off YC after this. Maybe early on it was a mark of quality and good due-diligence, but now I'd argue it's the outright opposite - if it's funded by YC, buyer beware.
They rather sell themselves as early-stage startup incubator.

"The overall goal of YC is to help startups really take off. They arrive at YC at all different stages. Some haven’t even started working yet, and others have been launched for a year or more. But whatever stage a startup is at when they arrive, our goal is to help them to be in dramatically better shape 3 months later."
