How is Google Search a public utility?

Comparing something to a public utility is not me saying it's literally a public utility. Google runs a monopolistic service that is essential to a lot of our public life, in a segment that has high cost of entry and infrastructure cost. They make the service worse to make more money. It should be a regulated utility like electricity or railroads, we should have a public alternative like the post office is to UPS, or it should be nationalized. The situation gets more dire when you consider their browser monopoly.
