Considering literally anything can be used to harm, kill, or maim (I actually have a friend who was severely injured by a pineapple) if used incorrectly, I say it's better to have open-source knowledge so we learn how to properly use something rather than sit in proprietary ignorance and hope nothing bad happens. Besides, knives, cars, guns, indoor plumbing, house wiring, etc., are all just as if not more dangerous than farming equipment. Just slap a good ol' MIT license agreement somewhere on your product so that it's clear to the user "if you do X, you void the warranty and you're solely responsible for whatever damage you might cause."
