I just installed Firefox on iPhone hoping to install ublock, only to realize that you can’t and the reason you can’t is because Firefox on iOS is just WebKit with a different UI. This made me wonder, given the recent rulings around the App Store, how has Apple gotten away with basically banning every other browser engine on their mobile platform but their own? Is there any current court cases - or are iPhone users basically stuck?
