I know it's being denied, but things got REALLY political after the internet shrank to the size of a thimble and world powers began exploiting that to fuck with people.
First, algorithms naturally try to show you things that will piss you off because it keeps you on their site to see more ads. Second, political operatives of many stripes use this to make you mad at whatever and whoever. When was the last time anyone threw shit over something of substance? We barely talked about the tax overhaul but let me bang my fucking drum on whether somebody was gay on TV.
It's just companies turning the lowest common denominator of frustrations into ad money, and moneyed interests forming a mutually beneficial relationship with that.
