The writer of that article has a book out..

It appears to be a libtard crybaby book about how the right used what he thinks are flawed social media systems to rise back to power. Translation: "Hillary didn't really lose."
He is essentially calling out the questionable content on the web because he knows it acts as a type of firewall between the first amendment and right wing political speech. In other words, Isis videos will have to be censored before they can make an argument that right wing political ("hate") speech should be censored also.
As Paul Joseph Watson pointed out in one of his videos earlier this year, the left dominates Twitter because their shallow arguments can fill 140 characters and the right dominates YouTube because video requires substance.
The left is desperately trying to find ways to stifle right wing video production.
