I don't see anything wrong with this monetization move. Chrome users don't pay Google for the use, so Google has no obligation whatsoever to make unpaid users as happy as their paid customers. And Goolge has(could) not set any barriers for competitors to come out with superior products. If enough people switch because their dislike, Google will adjust. It's market dynamics
The whole point of a monopoly is that you can leverage it to allow unfair advantages that allow your products to be worse for consumers and they have no choice but to accept it. As long as Google has search and browsers locked down they will have an unfair advantage in the direction of the web, one definitely not in consumer’s favor.
Whether it’s the government’s role to break that up is a political question, but Google is most definitely a classic monopoly and the internet is worse off for it.
