It's a deal when they stop updating. It is true they provide OS updates for longer than most, but many people use devices, especially ipads for way longer than the OS supported period. And those people are stuck on an old unsupported browser without being able to update or install a 3rd party one.
As I said in another reply, Apple just did a security update for the iPhone 5s released in 2013 January of this year.
The latest version of iOS runs on iPads back to 2919.
The latest version of Chrome requires the version of Android - released in 2019.
So how is it better?
