The following in red is confusing. Would you please paraphrase it more easily?
No one wants to see a few companies in charge of the world's food supply, so who owns the seed is a real concern. But this too won't last.....
It (Genetically Engineered) is a relatively simple technology that scientists... have perfected. The product of GE technology, a seed, requires no extra maintenance or additional farming skills. This means that GE is already democratic, provided that we can learn to share the intellectual property. This hasn't happened yet... but in a recent speech given at the Long Now Foundation, Michael Pollan called for an open source movement for GE crops. Stewart Brand agrees, arguing that "if Monsanto throws a fit, tell them that if they are polite, you might license back to them the locally attuned tweaks you've made to their patented gene array."
It's comparing GM crops to open source software, where you can take something and change it. If you grow Monsanto seeds, it implies that there will be changes made by the context in which you grow them, so you should be able to license this back to them instead of paying them for their intellectual property.
