Another is the part about people paying ad words for freedom or stuff they couldn't otherwise get. The fact that Google's system can reach more people and more cleverly than before is certainly a benefit. There were alternatives, though, like listing your product in online stores, Buy It Now on eBay with a link to a store, or mass marketing after buying listings of leads. Similarly take less staff than traditional marketing at big firms. The online ecosystem for ads also involves lots of fraud with estimates showing it is a good percentage of ad expenses. So, Google is actually yet another middleman in this sense that tries to lock you into their set of benefits and problems. They also try to shift the benefits toward themselves a bit more over time like any business. So, they're just middlemen with a bent toward lock-in rather than purveyors of freedom.
So, aside from the Google comments, other stuff was pretty interesting. Lots of historical and economic tie-ins to her analyses.
EDIT to add: I'm only through around half the post. It's pretty huge haha.

She also apparently worked at Google. Explains the bias. :)
