I like the idea of GMOs, being able to engineer plants to survive in harsher conditions and have a greater yield.

Unfortunately, they also like to engineer them to not produce viable seed. Roundup Ready canola/rapeseed can only be reseeded once, if I remember correctly, forcing farmers to purchase more seed to keep farming. And if there’s cross-pollination in a neighbouring farm, Monsanto likes to sue the neighbour for illegally planting their crops, despite it being the result of plants doing plant stuff.
