The issue is they specific said you can't start or use existing code before the date (still there in the rules PDF). I know that many very talented teams followed that rule even though theycould have used some of their older repos and did something even more impressive than Upshot. Then they respond to a forum question, weeks after the hackathon started, saying "yeah sure, just not a significant amount". Most programmers were heads down in their code and didn't check the forum. That's wrong and they did nothing to explain or correct this.
