They sue people who they think infringed their patents. Farmers who deliberately select out the Roundup resistant crops for replanting and/or buy the seeds illegally in contravention of patent law. I've read a lot of Monsanto vs. farmer court summaries, and I've not yet seen one where the farmer was not deliberately infringing. The article you linked to didn't mention any evidence that they have sued farmers who were simply affected by cross-pollination.
