The article does make a few good points, but I also think it uses a couple of unforgivable rhetorical devices. Most obvious are the out-of-context mentions of various "huge numbers", e.g. as follows:
"By reducing the need to till farmland, GR soy and corn have prevented 41 billion pounds of carbon dioxide from being released in the atmosphere between 1996 and 2013."
This amount of CO2 savings sounds great without comparison, but it amounts to about 0.003% of the total GHG emissions in the same period. (Assuming emissions of ~40 Gt CO2e/year 1993-2013 [1].)
