My recollection is that he loved that kind of thing... all of his books showed the clear signs that they were half or more about whatever thing he'd been reading up on and talking to people about lately. I'm sure I read several that had discussions at the back about the real-world aspects, bibliographies, acknowledgements, etc.

I haven't read it, but I know for sure that State of Fear, his book that revolves around eco-terrorists creating fake natural disasters to gin up fear about global warming, (in)famously has extensive notes and discussion about his views on the subject.

Depends on details. Monsanto doesn't worry about seeds on the wind. The cases I've read have come down to the fact that they escaped to someone who was trying to take those genetics. The farmer planted next to a round-up ready field, and then saved seeds - this would have been fine except the farmer then used those seeds and sprayed round-up which ensured all the plants without the round-up ready genes died and his next batch of seeds was all round-up ready. If the farmer had just used all the seeds without round-up Monsanto wouldn't have cared - at least so far as we have evidence, but then of course the farmer lacks the benefits of those genes.
