The point here is to highlight the actually cartoonish level of dysfunction and damage with an intentionally cartoonish flourish.
The "villian" in this case can be colorfully interpreted as the real world isomorphism of a mustache stroking, side sneering perpetrator, from any usually fictional world-stakes good vs. evil story.
Intentional exaggeration also communicates a bit of self-awareness, that gives heavy crisis alarms more credibility. The author's levity demonstrates a higher level awareness and humility, by making fun of his own extraordinarily serious thesis.
Finally: gallows humor. Add humor when talking about depressing things to relieve the anxiety that often inhibits discussion and contemplation of difficult topics.

Hyperbole isn't a knife. Any more than a political cartoonist's brush. It is satire. Biting humor.
The more ridiculous the caricature, the less you are supposed to take the details literally.
The "culprit" is a lightening rod. Taking the heat for what is obviously the result of a lot of people's seemingly poor or unfortunate judgements. Google search was a thing of beauty. Now it is an ugly swamp I have personally stopped trying to wade through.
