But they weren't full of shit. They made a vastly superior product. It made cider just as good as the Apple family, but could produce in much greater quantities. Their only flaw was overconfidence by allowing the Apples to use more people and then becoming flustered in the end.
Yeah, you're right. Their production was definitely better. The problem with them, besides their overconfidence, was their greed. As I recall, their deal was fairly nonsensical as it made no sense for the Apples (and probably apples used to make cider, too) aside from "we can make cider faster, and this edge in production is an economic victory that invalidates your method/allocation of apples over time." What does making cider faster mean?
In fact, maybe outright lying (being a real snake oil salesman) is what's going to happen this time around.
I kind of expect the plot to go something along the lines of this:
hehehe
Oh man. I hate Discord as it is. If we get a "Flim Flam Bros are benign ponies who market things" I'll be pissed. Why bother calling them Flim Flam at all? Will we be teaching kids the merit of subversion and looking past the surface.
