I think you are right, however it kinda seems they already put up with a lot more from companies selling them their 'patented' seeds and the constraints that come with those seeds.

I once saw a doc mentioning a farmer that got 'fined' by a seed company because he had some seeds he did not pay for in his crop, these few plants that grew because the neighboring farmer was using them and the wind blew some on the side of his lot. Also, they are no longer allowed to stock up on the seeds, they need to renew their stock... Has anyone seen this also?
