He is specifically talking about accessories, in this case the watches. including apple watches and 3rd party. if apple watches integrate natively, but 3rd party watches don't have the same level of integration then there is no way in the apple ecosystem to make a comparative decision on which watch you want to use as you're automatically funneled into apple watches by design. Now on android, most watches integrate pretty much the same. maybe a different on phone app, but, most APIs are pretty accessible between all devices. (I might be wrong about this)
