That article downplays SEO and mostly argues that Google is responsible, and it still gives Google way too much credit. I mean, it's gonna take a lot more evidence to make me believe they broke the internet by accident, for one. People knew all this crap would happen before Google was even a thing.
It already was someone else. I am old enough to remember when all these conversations (and the very accurate warnings about algorithmic filtering and artificial content promotion) being directed at Altavista and Yahoo.
