You can't do that, you certainly agreed to binding arbitration with apple at some point.
Unpopular opinion in these parts, but I think yes, they should be able to (continue) to sell products with lock in.
Where Apple should get in trouble is specifically locking others out, rather than locking their own stuff in. If Apple wants to make a smartwatch that only works with iPhones, fine. What they shouldn't be able to do is block (either intentionally or via undocumented/private APIs and TOS violations) third parties from making a smartwatch for iPhone that can compete on the same playing field as the Apple Watch, with access to all of the same features.
Same goes for all tech companies. If you want to lock-in your own first party products, fine, but you absolutely should not be allowed to lock-out others.
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.
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.
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.
Besides, I think this will create surprise and confusion for less technical users. In my experience, many will blame the incompatibility on whichever device is new, without understanding who is gating out whom. And even for technical users, consider CarPlay and Android Auto: From the phone’s perspective, the car is a peripheral, and that makes sense; but lots of people will still consider the car the “core device.”
