Roszak's notes also said that because users got hooked on Google's search engine, Google was able to "mostly ignore the demand side" of "fundamental laws of economics" and "only focus on the supply side of advertisers, ad formats, and sales."

This is textbook phase one of what Cory Doctorow calls "enshittification". Users don't have much of a choice, so make it as shitty as you are able without them leaving? Check. Phase two (which Google is no doubt also doing) is to do give the same treatment to the advertisers.

The pressure to maximize profits ensures that all private entities performing this sort of connection role on the internet will eventually become enshittified. There's no escape (under capitalism).
