In that article it was locals who got the witch doctor frauds to switch from bootleg alcohol to cola in their cermonies, so no direct link from that plant to them. It's local middlemen screwing over their own people and those criminal "healers" who now make more money from patients because it's easier and cheaper to obtain sodas than it is to make and sell alcohol. For sure a bad situation but if sodas weren't around they'd be drinking booze again and milk would still be too expensive, the water still undrinkable.
If you want to hold somebody accountable start with the guys peddling phony healing for dollars then move up from there to whoever is politically in charge of that region letting it go to shit, not hiring engineers and planners but instead cronies, and pocketing the rest of the federal money transfers. https://growthlab.cid.harvard.edu/publications/why-chiapas-p...
