Apple is not defending browser engine choice

As penance for this error, and for being short with Miguel, I must deconstruct the ways Apple has undermined browser engine diversity. As we will see, both the present and future of browser engine choice are squarely within Cupertino's control. Apple's prohibition on iOS browser engine competition has drained the potential of browser choice to deliver improvements. 5.48 The WebKit restriction also means that browser vendors that want to use Blink or Gecko on other operating systems have to build their browser on two different browser engines. Several browser vendors submitted that needing to code their browser for both WebKit and the browser engine they use on Android results in higher costs and features being deployed more slowly. 5.49 Two browser vendors submitted that they do not offer a mobile browser for iOS due to the lack of differentiation and the extra costs, while Mozilla told us that the WebKit restriction delayed its entrance into iOS by around seven years. Most substantially, iOS policies against default browser choice - combined with "In-app-browser" and search entry point shenanigans - have delayed and devalued browser choice.
