People who eat mostly rice are picky about the rice they eat.

Golden Rice 2 was on the market for about five years in the Philippines before it got banned. If anybody had wanted to grow it or eat it it could have been a different story. I was talking to a genetic engineer a few weeks ago who said that the sensory qualities weren't that great. Nothing would have stopped advocates in the US from planting a few acres and selling bags of it (it's approved and all) but had they done so it would have put the lie to the idea that the developers were being persecuted like Prometheus. I don't think it was anywhere near the threat that its opponents said it was but it was nowhere near the boon that its promoters said it was.
