Sure, you may agree with most of them, but what if you're the developer of an app such as a cryptic watch app for the Apple Watch, and then Apple decides to block all apps on the watch who's main function is displaying the time (like they did)?
I would say that the cryptic watch app was 'obvious' in my mind though. Watch faces are a well defined concept on the watch, and the lack of third party watch faces was about as explicit as one can expect from Apple. I'm not surprised at all, and ignoring the fact of whether they should be allowed, I feel they were skirting too close to the boundary to be able to complain about being removed, but that's just my reading of the situation.
