Back in the 40s Monsanto sued JI Rodale who started the organic
gardening magazine. He had told people that the stuff wasn't good for you and one of his young friends wrote a book called silent Spring which painted a dismal picture of the future with pesticides. Monsanto lost in this suit.
About 40 years later Monsanto decided to sue JI's son Robert Rodale. He was guilty of saying many of the same things about them. Monsanto lost this lawsuit as well.
Several farmers on the Canadian prairies have lost huge amounts of money because Monsanto sued them after their crops were contaminated with GMO pollen. The resulting seed was considered Monsanto's property.
I'm glad to see that they are now the defendants.
