I'm not entirely sure if the distinction you're making exists.
Let's say I'm Samsung and I want to make a phone that works with the Apple Watch. Isn't the Apple Watch locking me out? Apple is preventing third party devices from working with the Apple Watch.
I’m saying it’s fine for Apple to make first party tech that only works either their other tech.
Samsung not being able to make a phone to work with Apples first party accessory isn’t the problem.
The problem is Samsung can’t make a watch that functions on par with the Apple Watch on iPhones.
Having first party, integrated accessories is fine. Locking out third party accessories is the issue.
Whatever Apple makes first party for the iPhone , third parties should also be able to make for the iPhone with the same level of access and functionality.
I think the line between accessory and non-accessory is really slippery. When the iPhone was released, I think it would have been correct to call it an accessory for your computer. When did that change, exactly?
Heck, I don't really think of my Apple Watch as an accessory. Mine has its own LTE connection; it does need to be connected to an iPhone during initial setup, but after that I don't think there's anything stopping me from giving my phone away and using the watch by itself. Many of the children I teach have an Apple Watch but don't own a phone yet.
