It was a page that you dug up that boasted a lot of unfounded claims and also supported your theory/ideology. By aligning yourself with that author you make your own arguments just as bad. Sure patents and greed are bad but that is completely besides the point (you implied PLA bad because it is 'genetically modified').
As you have already acknowledged PLA does not contain any genetic material and only uses GM maize because it is the cheapest source in the US, I consider your argument completely ideological. I don't think that is a good basis for any discussion, as we will not be able to convince each other that I am right.
So go ahead, post your reply praising your own ideology (and be done with it).
