but this can change. At least in the EU Apple already prompts a user which browser they want [1]. While at the moment every browser is WebKit under the hood, this will probably change as the EU is also pushing Apple to allow other engines [2] - and with users knowing Chrome from Ads, their work or from a previous Android phone, I can imagine a lot of them selecting Chrome as a default.
