> Also, most users are not aware that third-party iOS browsers like Chrome, Brave, and Firefox are actually just light UI "skins" on top of the Safari browser engine, Webkit. Apple refuses to allow third party browser engines on iOS.

IME even a lot of developers are unaware of this fact.

An added annoyance flowing from this is that Apple does not allow remote debugging for webviews, so any reasonable debugging flow for those browsers is blocked. Great fun when you have a bug in iOS Chrome only.
