Barnaclebob,
I read part of the link you provided - particularly the story of Schmiezer whose canola crop was exhibiting over 50% of Monsanto's GMOs. That particular "mythbust' was so weak. They claimed that there was no such case of Mansanto suing a farmer whose crop was infected by the GMO. Then provided a perfect example of Monsanto doing just that very thing. Then the article tried to dismiss it as myth because this wasn't a situation where Monsanto sued for a little bit of cross-pollenation.
In this case Schmiezer deliberately selected for those plants that had been cross-pollinated and re-planted them the next year giving a greater than 50% rate of GMO containing plants. Schmiezer did not "steal" the GMOs. He did not copy Monsanto's methods. He did not even enter into a purchase agreement with Monsanto and break that agreement. He merely gathered seed that was on his own property and planted it again. He was clever enough to know that the GMO was Roundup resistant so before gathering the seed, he killed off all those plants that were not resistant by applying Roundup. But the genetic material came from the neighbor's field through natural and uncontrollable means.
Schmiezer sort-of won the case, and of course the story did nothing to illustrate what Schmiezer went through to defend himself. Defense attorneys are not cheap. And this wouldn't be the first time where a company knows full-well that they may not win in front of the judge, but the mere act of dragging your opponent into the courtroom can be sufficient bullying tactics to get your desires met. (just like a playground bully - it is often the THREAT of a fight that gets them what they want, but in order to get them to stop they have to be soundly beaten.)
