You're missing their point
Many are frustrated with agribusiness because of their refusal to adopt better practices as they are developed. They intimidate farmers to by their over priced chemicals by convincing them they won't be profitable if they grow their crops and live stock naturally. If that doesn't work they attack them. Monsanto for example successfully sued a Saskatchewan farmer for not using their products.
We don't like it when people knowingly threaten the well being of everyone for their own profit.
