If farmers want to pay for seed stock of known features and quality, that's great. What they do after that should be totally under their control and domain. A legal precedent for interfering with the ancient practice of saving seed and selection of seeds from desirable plants is so entirely "evil" I can't explain it to someone who doesn't "get" it already. The evilness or any corporate control of genetics in the wild (outside of their production labs) should be self-evident.
I laugh at the audacity of garden catalogs that warn that you cannot take cuttings of certain patented items, like thornless blackberries. Blackberries are stupid-easy to propagate with cuttings, and it is completely absurd to think that people will (or should) obey such a warning.
