the righteousness of waving the science banner aside, the gmo-corn story is far from over. although gmo species may have beneficial properties such as higher yields or greater resistance, there are many strategies for targeted genetic change, not all of them good. for example, targeting pesticide resistance allows for greater yields because of increased pesticide use. the system wide effect of introducing a new species, GE or not, and the options for different agricultural practices are hard to predict. since there are only destructive tests for this kind of thing, being prudent is not a particularly bad approach.
also, in the post-modern world, everyone has an agenda and is, therefore, in conflict of interest. there is no moral high ground and righteousness is an enemy of the truth.
