There are groups who want to keep the folk under control.
What's the first thing to do to control a specimen?
Monoculture. But they made a mistake in their concept: the weaker genome of the new monoculture is breaking and the distributed sample will collapse.
Poisoning the polyculture may or may not work. If it works, there will be no specimen left.
Why would God let those survive who feast on the forbidden?
