It's relatively simple and easy to change your default search engine and/or type in a different url, in fact, it quite literally costs you $0 (as in - it doesn't cost you any more to use ddg over google), so digging a well, and the further cost of routing your pipes to pull from that underground water is infinitely more expensive to do. This is the principle behind utility companies being regulated: it's insanely expensive to do the alternative of using that utility company. Now, Apple and Google (in terms of Android) might need to be considered some sort of public utility (eg. providing an app store) since it would cost competitors tens of billions of dollars to match the existing ecosystem, but Google Search is far from being considered a utility.
