Who put a group of people in a room and thought it would be a good idea to:
1. Change the forward and back swiping functions when playing a video to only work if done on a tiny portion of the screen?
2. Came up with new sounds, and then decided, hey, let's not let people change the default sound for the alarms, so when they tell Siri to wake them at a certain time, we will play what has to be one of the softest sounds we have. We don't want to upset our customers by actually disturbing their sleep and waking them up.
You literally paid people to break something that was working well and make it worse.
The only explanation has to be that you are heavily recruiting Microsoft Employees and then allowing them to come up with stuff like this.
