This is just nonsense, it is extremely easy for farmers to buy non-GMO seed. Not only are there several other huge seed producers (Bayer, BASF, Dupont, Syngenta, Pioneer, etc.) that sell high-quality non-GMO seed, but there is a huge ecosystem of regional cooperative seed producers that make decent seed.

Farmers choose GMOs because they really do get more return on their investment. They aren't idiots and they aren't being forced.

Microsoft uses compatibility and bundling as leverage to maintain their monopoly

ATT/Verizon use municipal contracts and large barriers-to-entry to maintain their oligopoly

All Monsanto has are patents on their specific crop strains. What prevents a seed producer from going into business other than the benefits of using Monsanto strains?

EDIT: ok, after googling around (the techdirt link was broken), it looks like they were bundling

As a grain farmer myself, I don't know this to be true. In fact, the only GMO crop we do grow is field corn because there is no advantage of non-GMO varieties in that crop. Perhaps you could elaborate some more?

False. There are several competitors like Dupint, Dow Chemical, and Bayer.
