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.
Chrome and Google being bad doesn't make Apple's restrictions good. That said, Android lets you install a 3rd party browser which can choose to keep supporting old devices. iOS locks everything to using the safari engine.
