Earlier quoted context omitted.
I suppose it is possible that large agribusinesses where you live do this... it is also possible that the small farmers near you have an axe to grind with their larger competition, and/or are open to accepting and spreading gossip and rumors without much basis in reality.
But you don't think it's possible that all the incentives are geared towards this kind of behavior?
But I would caution against taking rumor and gossip as strong supporting evidence.
