Randy Constant wasn't selling organic produce, or really much of anything that you think of buying "organic" at the grocery store. Because, for the most part, there tend to be a lot of visual differences between organic and conventional: conventional apples, for example, tend to be huge and spotless, while organic are almost always smaller and less "pristine". Similarly, stuff like organic, grass-fed milk tastes much different than conventional milk.
I've always been of the opinion that, as a consumer choice, organic makes sense for certain types of products where you eat the skin and all, e.g. apples, vegetables, etc.
In this case, though, Mr. Constant was selling "organic" grain primarily as livestock feed. The idea that you can really tell, or there is any difference at all, in the meat of livestock fed organic vs. conventional is extremely far fetched. Sure, there way be some tiny difference, but it's not like conventional methods include spraying with heavy metals. Most of the pesticides, etc. sprayed on conventional crops certainly don't show up in the meat of animals that eat these crops.
So this whole episode did expose the scam of organic livestock feed, but I don't think it's fair to stretch that to organic products generally.
