@damianogerli I think there are some things in the original google paper which also didn't age well.

infolab.stanford.edu/pub/paper

For example the section about "Advertising and Mixed Motives" with quotes like "The goals of
the advertising business model do not always correspond to providing quality search to users" or "[...] we believe the issue of advertising causes enough mixed incentives that it is crucial to have a
competitive search engine that is transparent and in the academic realm."
