I covered that in my post, please keep up: Chrome for iOS is powered by Safari on iOS, because Apple refuses to allow any other developer use the developers own code and libraries. Chrome is prevented from using Google's inhouse Blink rendering engine and the majority of the rest of the Chrome code and features we know and love on every other platform including Android.
Chrome is forced to use UIWebView, which is an OUTDATED and OLDER version of Safari than Safari.
If you use Chrome on iOS, you are getting an INFERIOR browser because Apple dictated that all other browsers must A) use Safari as their internal and B) must use outdated and old versions of Safari so they don't and can't compete with Safari fairly.
Which is MY WHOLE POINT, really, that Apple holds back innovation.
