After you install the 17.4 update or when setting up the phone it'll ask what browser you want as your deafult. Before this and still in other countries you have to manually search and download a browser and set it as the default.
yes, because the average user doesn't even know there are different browsers, and that they can change the default one, which is great to "vendor lock" your own browser, in this case Safari from iOS
Some might be aware others exist but not be quite tech savvy enough to figure out how to have it be the default. I downloaded Firefox for my ex on her phone but the default was still chrome so whenever she clicked a link on an app it would just open on chrome. If this pop up had happened she would have chosen to make Firefox her main browser when opening links and stuff. She did use it when browsing normally, Chrome was just the default for all other apps.
Hell you dealing with iPhone users here, they barely know that the device they use in this technically a computer. You've got to basically spoon feed them basic stuff like other browsers exist.
IPhone and Mac users in general. A friend of mine was an Apple sales rep for many many years and holy crap I dont know how he didnt go on a killing spree
I used to work for Apple technical support and the stupidity of your average Apple user drive me up the wall, it's left me with a very negative view of their clientele.
My favorite was the person that threatened to sue me personally because he had dropped his iPhone on a glass table and it had broken the glass table and the iPhone. And he was mad that Apple wouldn't cover his costs.
