Here's something I don't understand.<p>If you want to switch your search engine for Safari on iOS, you open Settings, tap Safari, tap Search Engine, and tap your preferred search engine. Not many users do this, and the conclusion is that the default has an unfair advantage.<p>If you want to make Chrome your desktop browser, you open the default browser, search for Chrome, click the correct result, download the installer, run the installer, open Chrome, and set it as the default browser. So many users do this that people conclude Chrome has an unfair advantage.
