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.
