I don't know about that, this one was at the college I used to work at before and I got to mentor two young developers and I continue to mentor one of them. Not everything is as bad as people might think, and some developers work different from others. We saw some amazing projects out of TADHack Mini.
Lastly: Nobody has our code but we ourselves. It really depends on who hosts the Hackathon and the purpose of it. We've heard of businesses being bootstraped directly out of this specific Hackathon.
