You’re link isn’t even about the “cross pollination” situation (which was also done intentionally by the farmer) but about someone buying the seeds from a third party and then claiming that they are allowed to replant the seeds because they aren’t bound by the licensing agreement.
We can argue whether or not this farmer should be allowed to replant the seeds in this case, but trying to paint it as if the seeds flew into his property and then he was sued for it is a disgusting misrepresentation of what actually. It was done very intentionally by the farmer. They aren’t some innocent victim, but one who thought he could get the ip without paying for it. We’re talking about capitalists fighting each other.
