The point is that this amazing story could be produced, as a finished movie, by a team that only needed to raise about $3M. Precisely how much of that is because they used Blender is still not clear to me, but the importance of Blender's use here is that it opens the door to equivalently great (or even better!) story telling on (relatively) low budgets ($3M is still a lot to raise, it seems to me). This story would never have been made if it needed $30M or $300M to make.
