I've always thought this was part of The Plan, so to speak, part of the swamp dredging. Create an environment that appears to be in favor of the darkness, that gives them the impression that they rule the proverbial roost, in order to embolden them to come right out and proudly show others what's truly inside themselves, to display their true characters.

Case in point Ms Peterson here - had this incident never happened, good people may have continued to support her business thinking she was a decent person, but now that they know better they'll choose a different yoga studio. People's true natures are being exposed.

Will Ms P here do some soul-searching and find her way onto the right path? All up to her - her choices, her consequences. For her and all the others living in darkness, embracing evil, they may choose to feed off the exposure, as you say, but when exposed to the light it's inevitable that their end is forthcoming. Will her business survive? Doubtful though it may take some time.
