Cracker Barrel came out with a logo, and everyone hated it. I personally hate that they serve very few crackers despite the promise of having barrels full.
Why did people hate the logo? You could throw a dart at a board of reasons why people get angry at anything these days. Any answer you hit will likely suffice.
But why are there so many reasons people get angry these days? The vast majority of it is manufactured, whether folks are aware of it or not. Anger is the easiest route to engagement, and engagement is what drives the economy of social media.
