I am starting to see this trend where hackathons are more about investors bringing an undercover team to pretend they formed a team and code for 2 days, while in reality. The team was formed a while ago, product was pre-cooked, actually more like ready to be served. And just need it an event to get some PR. Hackathons should have a (literally) Code of Honor. Judges should be hackers and they need to make sure there is no code before the event and do a code review before the judging.
