Google is darn near close to a monopoly on search (at least, Peter Thiel made that the premise of Zero to One), which isn't to say they're also a monopolist in every other field they're in.

I like Google since they're one of the few companies that has a 20+ year record of being careful with user data, but how much they control (or at least facilitate) is pretty scary from an objective viewpoint.
An information good is one for which it's very cheap to produce additional units. Unfortunately, I'm probably abusing the term, since books are listed as an example of information goods. The idea is that most of the cost of producing the book goes into the content (writing, editing, etc.) and actually printing one additional book is cheap. (When I said books are "imperfect" information goods I meant that they still require paper and shipping and retailing and such, but it's probably just a bad use of the term.)
There's a fantastic book about the economics of information goods called "Information Rules" ( https://www.amazon.com/dp/087584863X ). Software is an information good so this covers some topics relevant to the digital economy. My favorite part is the chapter on lock-in. In particular the discussion around the equation:
profits from a customer = quality advantage + switching costs
which puts "(marginal) goodness of your product" on equal footing with "pain you can inflict on your customer for leaving".
If Google is the monopoly in the sense that the OP describes, then a unified Internet itself is a bigger monopoly. Break apart the monolith of the Internet itself, and you have more player contending equally in facilitating search etc.
