I have a very capable smartwatch and it's ridiculously bad how hobbled it is on iOS. I'm glad to see this article specifically highlight the issues, and how it's 100% Apple's intention to make non-Apple wearables on iOS terrible.
Because everyone here commenting knows the reason?! This is all speculation by outsiders. Apple isn’t commenting and if they did, outsiders wouldn’t know if it’s the real reason. It could be that Apple lacks the patents, for some of these key features and they are making the best out of a bad situation. It is what it is and we can’t be sure why.
The law doesn't care why they choose to do it. The result of the decision is what constitutes illegal monopoly behavior.
