It is not selfishness nor altruism. It is their execution. Anyone would be dumb not to see that Google through this project is trying to milk people for ideas for nothing in return. We all want to help that is true (well besides the psychopaths and that's like 2% of the population) but if someone else is profiting from my help, the way Google most probably would, is just hurtfully cheating.
