I highly doubt that people are going to de-fund the OUYA project in large numbers. And what is the point of actively encouraging people to remove their pledge anyway? By now, I would assume just about everyone on kickstarter understands that there is a good deal of risk involved. Even if this project never makes it off the ground, people are giving OUYA money not necessarily for a console, but for the dream and hope of the disruption that the project will bring to the market.
