If they would only verify quality and provide safe APIs and paths to safely integrate they can have their platform. The issue is that they are both managing the plantform and (unfairly) participating themselves.

If they had one set of APIs for smartwatches that can be used by them for the apple watch and everyone else for their smartwatches they wouldn’t get sued. But instead they give themselves deep integration into the OS and limit everyone elses access. When you are one of the only available platforms thats not okay.
