I read the article. I think it's being deliberately obfuscatory. It did not make clear whether the restrictions would apply to all seeds, to a particular group of banked sends, or specifically to GMOs purchased with this provision already in the contract. I suspect the reason they're waxing ambiguous is that it's the latter of that list and they want to make it sound more nefarious than it is.
