Lame. Every electronic device has a disclosure from the FCC that says your electronic device must live with/accept any and all external interference that may affect its proper operation. Want your electric guitar and amp to sound clean? it is YOUR responsibility to get clean power, use shielded cable, and record inside a Faraday cage or whatever.
So now, you are saying, that if I farm on MY land, and my plants go to seed and the wind, an act of God, blows those seeds on to your property, that *I* am responsible for that?
Seems like Monsanto needs to build a high wall or enclosed greenhouse if they don't want contamination from outside their property. They need to control their own conditions, I don't need to contain mine.
Sheesh.
