Apple only allows the Safari browser engine to run on their phone.
So Google (and other web developers) can't do what they do on other platforms which is only test their website on Chrome or block users of other browsers.
For example, Firefox on Android gets a crap Google search from like 2005 unless you spoof your user agent and it works perfectly.
By that mandate has kept complete control over the browser space from Google.
I've very rarely seen a website block a user because of their browser in the last 10 years.
If a website doesn't work in Safari, it just doesn't work. That's it. I do know that devs have to work A LOT harder to get things to work in Safari when compared to Chrome or Firefox. It's like Safari is the new Internet explorer.
