When Apple first said they would only allow a single web rendering engine on iOS, at first I was heavily against the idea. But now as a web developer who is absolutely not looking forward to the inevitable "people running around with 10 version out of date Chromium browsers", I'm starting to think Apple had the right idea. I can test a website on a single iOS device and know it will work the same on all devices in that version of iOS even if they are using "Chrome on iOS" or "Opera on iOS" or any other browser. I have no idea how I'm supposed to test a site for 13 different Chromium forks. And as time goes on, they will only grow more and more divergent from the main Chromium branch, which means they won't have bug fixes or new features.
